Information

First, the necessity of revision of the blasting safety regulations GB6722-2003

  1. The blasting safety regulations GB6722-2003 has been in operation for 7 years since May 1, 2004. The standardization and rapid development of the blasting industry has played a due role in ensuring the safety of blasting operations and reducing blasting accidents. Praise. In the past seven years, with the implementation of people-oriented and national concept of governance, all departments have attached great importance to safety production. Some regulations and methods related to blasting safety work and some national standards cited in GB6722-2003 have been revised. Edited and released, including

 

  1) The Regulations on the Safety Management of Civil Explosives (Order No. 466 of the State Council of the People's Republic of China) was revised in 2006 and will be implemented on September 1 of the same year;

 

  2) GB50089 "Safety Code for Civil Blasting Equipment Engineering Design" is a normative reference document for "Blasting Safety Regulations", which was revised in 2007 and implemented on August 1 of the same year;

 

  3) GB50154 "Safety Code for Underground and Overburden Gunpowder Explosives Design" was revised in 2009 and implemented on September 1 of the same year; the national standard is also a normative reference document for "Blasting Safety Regulations".

 

  4) The Ministry of Public Security has issued and forthcoming ministerial standards, which require:

 

  1GA837-2009 "Safety Requirements for the Storage of Civil Explosives" was promulgated in 2009;

 

  2GA838-2009 "Safety Regulations for Small Explosives Repositories" was promulgated and implemented in 2009;

 

  3 The “Safety Management Measures for Blasting Operations” has been submitted for review and will be released soon after approval.

 

  In contrast to these standards, regulations, methods, and requirements that have been revised and newly released in recent years, there are many contents in the "Blasting Safety Regulations" GB6722-2003 that are not applicable or contradictory to the newly issued specifications. They need to be revised or abridged. It is necessary to supplement and improve the relevant regulations and standards that are being implemented.

 

  2. The 7 years since the implementation of the blasting safety regulations 6722-2003 is the seven years in which all kinds of undertakings in China have flourished and the development of science and technology has advanced by leaps and bounds. The development and progress of China's blasting industry in the past seven years are mainly manifested in the following aspects:

 

  1) Drilling and blasting machines have been widely used and widely used. The main drilling machines and mixed vehicles are very close to the level of developed countries, which is the basis for promoting the development of the blasting industry;

 

  2) Due to the wide application of drilling and blasting tools, some traditional blasting techniques have gradually withdrawn from the historical stage. For example, blasting of pots has been banned, and open blasting has also been banned. As a shining example of blasting in China, The blasting process of the dilapidal room, which has made great contributions to the development of the national economy, has seen a significant decline in both the frequency of use and the scale of blasting in recent years;

 

  3) With the development of the blasting equipment industry, a number of civilian explosive devices that have occupied the main position for decades have been retired and eliminated, and the blasting process that is compatible with them must be retired and eliminated together, such as fire detonators and fuses. Production has been banned, and the "cannon blasting method" that is compatible with it is inevitably no longer radiant; 2# rock explosives stop production due to the addition of TNT to affect the health of workers, and the processing of the medicine package and the charging process are also withdrawn. The scope of engineering blasting.

 

  4) With the application of fully automatic high-precision hydraulic rock drills and on-site mixed-loading vehicles, with the emergence of new detonating equipment and the application of new explosives, the management of blasting technology and blasting engineering has been upgraded to a new level, which requires the vomiting of new The 7-year "Blasting Safety Regulations" have been added, deleted, and modified to meet the current process level and safety management needs.

 

  3. With the rapid development of the blasting industry, there will inevitably be a situation of good and bad, and there will be some “small, chaotic and poor” blasting units with low technical functions, chaotic management and frequent accidents. The blasting industry needs to be rectified. . To this end, China's blasting community has put forward the concept of fine blasting, eliminating some backward processes and high-energy, high-pollution, high-acceleration operating methods; the Ministry of Public Security will soon introduce the "Blasting Operation Safety Management Measures" for blasting enterprises. Rectification and restructuring. To support and support enterprises with strong capacity, standardized management, and safety, and to limit and renovate small companies with frequent accidents and low capacity, it is necessary to support them from the system. This is also an important issue to be solved in the revision of this procedure.

 

  In the past 4.7 years, some unforgettable blasting accidents or secondary accidents related to blasting operations have occurred. After analyzing the statistics, let us remember that it is unforgettable and painful. There are many accidents that require us to reconsider, learn from education, and need to be further knocked down. Alarming the clock, turning the education of the accident into the experience of preventing, reducing, and eliminating accidents, and then sublimating the formation of standard provisions, included in our revised "Blasting Safety Regulations", this is the best comfort for the victims, The best comfort for the injured, this is our responsibility, but also for the valuable property of the people in the world.

 

  Second, the principle of revision

 

  1. The revision is not a new one. It should be carried out in detail on the basis of the original standard; the deletion, addition and modification should explain the reasons; the length is controlled within ±10%, and the revised standard is a mandatory standard.

 

  2. Consistent with existing relevant standards, regulations, and methods;

 

  3. Delete the regulations related to the blasting methods that have not been used, increase the safety regulations related to new technologies and new technologies, fully reflect the advanced and practical standards of the revised standards, and pay attention to international standards.

 

  4. Summarize the lessons of the accident and sublimate it into standard provisions.

 

  5. Support advanced, limit backwardness, and promote the reorganization and integration of the blasting industry.

 

  6. Group revision, focus on discussion, and solicit opinions from many parties; revised drafts, discussion papers, drafts for comments, drafts for review, and approvals for five revisions to form the final standard text.

 

  Third, the changes in the main structure

 

  1. The normative technical requirements of this standard have all become mandatory. For this reason, the non-mandatory provisions of the original standard have been revised and abridged.

 

  2. Under the premise of a slight decrease in the standard amount of text, the 7 chapters of the original standard are revised into 14 chapters. The main changes are:

 

 

  1 Chapter 4 of the original standard (the basic provisions of blasting operations) is divided into three, namely

 

  Chapter IV Classification and Management of Blasting Engineering

 

  Chapter V Blasting Design, Safety Assessment and Safety Supervision

 

  Chapter VI Basic Provisions for Blasting Operations

 

  The fourth chapter is organized as follows: grading and level adjustment of blasting engineering; grading management of blasting operation units and correspondence with blasting engineering grading; conditions and responsibilities of blasting operators and grading management of blasting technicians, blasting technician level The relationship between the scope of work and the classification of blasting works.

 

  In the management of blasting personnel, training content has been added.

 

  The fifth chapter is the technical supervision and management content, and the three technical management business forms of design, safety assessment and safety supervision are taken out to form a chapter. The design procedure has been greatly revised. The original standard for safety assessment and safety supervision only provides for the principle that the project needs safety evaluation and safety supervision, and the safety assessment and safety supervision reasons are made. What is the content? In the revision, the situation of the implementation of the regulations in the past seven years was summarized, and the contents of how to conduct safety assessment and safety supervision were added, and the authority and authority of the regulations were more specific.

 

  Chapter 6 is the content of the "basic regulations for blasting operations". According to the process of blasting operations, the safety issues of each link are mandatory. Compared with the original standard, only the safety regulations related to the process of elimination are deleted, and the content related to the new process is added.

 

  2 The original Chapter 5 (Safety Regulations for Various Blasting Operations) is divided into six chapters according to different types of blasting operations. The order of arrangement is arranged according to the different blasting media and working environment;

 

  Chapter 7 is aimed at open-pit blasting operations, including deep hole, controlled explosion, shallow hole, frozen soil, and diverticulum. It has been deleted and simplified for chamber blasting, and it is expressly stipulated that bare blasting should not be carried out in open-air operations.

 

  Chapter 8 is underground blasting, including safety regulations for wells, tunnels, and various types of underground mine blasting.

 

  Chapter 9 has made systematic safety regulations for blasting operations in high temperature open pit mines, underground mines, high temperature and high sulfur mines, and hot condensate.

 

  Chapter 10 lists underwater blasting into a single chapter, including various types of underwater rock blasting, soft foundation blasting, ice blasting, and diving blasting.

 

  Chapter 11 is for demolition blasting and shallow hole blasting in towns. Both types of blasting are carried out in towns and cities. The operating environment is complex and there are many commonalities in safety management. The blasting of cofferdams, dams and retaining rock ridges was identified as one of the demolition blasts, so it is also included in this chapter.

 

  The title of Chapter 12 is special blasting. The blasting not covered by the above five chapters, that is, the blasting technician's safety operation certificate and the marked special blasting are all included in this chapter; or other blasting by non-rock blasting and demolition blasting Into this chapter. It includes metal media blasting, seismic exploration blasting, oil and gas well blasting and borehole blasting. The metal medium and oil and gas well blasting are special blasting industries with high output value, good efficiency and rapid development, and they occupy the largest space.

 

  The contents of Chapter 13 are safety and environmental protection standards, and the contents of the explosives library safety in Chapter 6 of the original standard are moved to Chapter 14. The safety and environmental protection standards have absorbed the experience and lessons of recent years and made necessary modifications.

 

  Chapter 14 focuses on the entire safety management of blasting equipment purchase, storage, transportation, management, and destruction and reprocessing. In line with current standards, the integrity of the content is maintained.

 

  After this arrangement, the organization is more clear, the title is more eye-catching, and it is also a bright spot for this revision work.

 

  3. Cancellation of Appendix A, B, and C. The relevant content has been amended to incorporate the formal provisions of Section 5.2 of Chapter 5 as amended.

 

  4. Description of the revision of each chapter and section

 

  1. The preface clarifies that the normative technical elements of this standard are mandatory, which is also the premise of this revision work.

 

  2. Chapters 1 and 2 only made textual changes.

 

  3. The terms and definitions of Chapter 3 have been increased from 31 to 38 of the original standard. All definitions have been corroborated by the relevant national dictionary. Some definitions of terms have been revised by dictionary.

 

  4. Chapter 4 Classification and Management of Blasting Engineering

 

  This chapter includes the classification of blasting engineering, the classification of blasting operations, the hierarchical management of commercial blasting operations units (the grading method is issued by the Ministry of Public Security documents) and the management of blasting personnel. These three parts are independent and closely related. The core content of this chapter is: grading the blasting project, the blasting engineering of different grades is undertaken by the blasting operation unit of the same level or high level, and the undertaking unit must have blasting engineering technicians that are compatible with the engineering grade and working range. Blasting projects that are not included in the grading management are not required to assume the level of the unit, but should have blasting technicians with appropriate operating ranges.

 

  4.1 Classification of blasting works

 

  1) Compared with the original standard, the blasting engineering classification table has made important adjustments.

 

  1 The scope of operation has changed from seven categories to rock blasting, demolition blasting and special blasting. Rock blasting includes open air, underground and underwater.

 

  2 Chamber blasting is no longer listed separately in the classification table and is specified in the classification note 1.

 

  3 The rock blasting column corresponds to the open-air deep-hole blasting grading. The open-air deep-hole blasting consumes more than one million tons of explosives per year. It is the most widely used blasting process that consumes the most explosives every year. There is no Class A project in the original standard grading. The adjustment was made twice; because it is no longer necessary to consider the level of conventional blasting in the mine, the corresponding doses of C and D grades are adjusted towards small.

 

  4 Underground medium-deep hole blasting classification, open-air and underground chamber blasting engineering grading, complex environment deep-hole blasting grading, and underwater blasting engineering grading are all rock blasting, which is specified in Note 1.

 

  5 The demolition blasting grade has undergone major changes, and two grading standards have been proposed. The building and factory buildings are judged according to the height. The blasting of chimneys, water towers and cooling towers is due to the high-rise buildings. 2 is stipulated; the amount of demolition blasting for cofferdams, dams and rock ridges is relatively large, and the classification is separately specified in Note 3; bridges, supports, foundations, floors, and singles do not involve height problems, only According to the classification of the total amount of blasting, it is specified in Note 3.

 

  6 The shallow hole blasting in the town has similarities and comparisons with the foundation, floor and single blasting. The grading method is also the same, which is explained in Note 3.

 

  7 The largest scale of special blasting is explosive compounding, which has developed rapidly. Many large and medium-sized enterprises have appeared in standardization, but there are also many small enterprises with poor technical conditions and poor management. There is no guarantee for quality and safety. After several studies, this time In the revision, the explosive compound is taken out into the category of hierarchical management, and standardized management is carried out, which is divided into three levels: A, B, and C.

 

  Other special blastings have not yet implemented the conditions for hierarchical management, and no hierarchical management is implemented.

 

 

  84.1.2~4.1.5 The grading of the blasting project was adjusted. The original standard stipulated that the design, safety assessment and approval unit agreed to improve the management level of the blasting project. This regulation is not easy to control and has certain randomness. The revisions clearly stipulated the B, C, D grade rock blasting project, the mandatory grading method for the demolition blasting project, and proposed a mandatory level adjustment table for special blasting, especially for the single composite plate. The provisions of -1, but the adjustment standards meet the requirements specified in Table 4-2, adjusted according to Table 4-2.

 

 

 

  4.2 Blasting unit

 

 

 

  The classification, level conditions, and bidding methods of the “blasting operation unit” were detailed in the document “Safety Management Measures for Blasting Operations” of the Ministry of Public Security. This revision made major revisions in this section. The purpose of the revision is with the Ministry of Public Security. The relevant provisions in the "Safety Management Measures for Blasting Operations" are consistent. The revised content is: the blasting operation unit should hold the certificate operation, and the operation certificate is divided into two categories: non-commercial and commercial blasting operation units. What can be done by these two types of blasting operation units, what should be done according to what procedure, and what can not be done. What are the security responsibilities, the principle of penalties for accidents and the requirements for file management. Basically all are newly compiled content.

 

 

 

  In particular, in order to prevent the commercial blasting operation unit from undertaking the grading of the unit after the qualification level is obtained, the blasting project that does not have the corresponding technical level and management capability shall stipulate that the scope of the blasting project shall be subject to the qualification level of the unit and There are double constraints on the scope of operation of technicians (specific constraints are specified in the “Safety Management Measures for Blasting Operations” of the Ministry of Public Security).

 

 

 

  4.3 Blasting personnel

 

 

 

  Because the "blasting operation personnel" is defined in the document "Safety Management Measures for Blasting Operations" of the Ministry of Public Security, it refers to blasting engineering technicians, safety officers, blasters and custodians. The provisions of this section also involve management personnel, etc. For "blasting workers". The basic content is still the original standard and the provisions of 4.2.4, only the following changes:

 

 

 

  1) Defining the original “blasting work leader” as the leader of the blasting operation unit, the person in charge of the blasting technology, the person in charge of the project, the person in charge of the blasting technology of the project, and stipulates that all should be trained and certified; the blasting equipment is clearly defined. The escort work was carried out by the blasters and security officers, and the full-time escorts were removed.

 

 

 

  2) It is clearly stipulated that the blasting operation personnel can only be employed by one blasting operation unit, and it is not allowed to work part-time in other blasting operation units.

 

 

 

  3) Mandatory provisions for personnel training.

 

 

 

  5. Blasting design, safety assessment and safety supervision

 

 

 

  The main provisions of the original standard 4.3 (blasting design), 4.4 (blasting safety assessment), 4.5 (blasting engineering safety supervision), and 4.6 (design approval) are combined with the relevant provisions of the Ministry of Public Security document "Safety Management Measures for Blasting Operations". In the past seven years, in the aspects of design, safety assessment, safety supervision, new cognition, new experience, new methods, and revision of the cost chapter, the main revisions are:

 

 

 

  1) Design, safety assessment, and safety supervision require units and personnel to have corresponding qualification levels and scope of operations, and bear corresponding legal liabilities and joint liability for the projects undertaken.

 

 

 

  2) Modification of design provisions

 

 

 

  1 The three-stage design document was designed as a single blasting technology, and new regulations were made for technical design and construction organization design.

 

 

 

  2 Appendices A, B, and C are revised and incorporated into the mandatory provisions of the design.

 

 

 

  3 The scope, procedures and authorities for design approval have been greatly revised with reference to the provisions of the Ministry of Public Security's “Safety Management Measures for Blasting Operations”.

 

 

 

  4 The materials to be submitted for design approval are specified.

 

 

 

  3) Security assessment and safety supervision provisions

 

 

 

  1 The assessment and supervision objects are clearly defined. Only the blasting projects with A and B grades and complex environments that have a greater impact on people's livelihood need to conduct safety assessment and safety supervision.

 

 

 

  2 Clearly stipulate the qualifications of the evaluation and supervision units.

 

 

 

  3 The safety assessment adds mandatory assessment basis, expert consultation, and mandatory requirements for the substantive requirements of the assessment.

 

 

 

  4 For the supervision content, the supervision signed the design documents, the power of the suspension order issued by the supervisor was mandatory, and the supervision procedure and the supervision summary report were also mandatory.

 

 

 

  These modifications were made after the safety assessment and safety supervision were included in the blasting procedures for seven years and accumulated valuable experience and absorbed the work lessons.

 

 

 

  6. Basic regulations for blasting operations

 

 

 

  Compared with the original standard 4.7~4.16, the order of preparation has not changed much, basically it is written according to the blasting process, and the content has been increased or decreased according to the state of scientific and technological progress in recent years:

 

 

 

  1) The environment for stopping the operation: The wind and wave environment was adjusted according to the site experience, and unified with the relevant regulations of underwater blasting: the original standard wind level is 6, the wave height is 0.8m, the wind level is 8 and the wave height is 1.0m.

 

 

 

  2) Provisions are made for blasting (rescue and disaster relief, related regulations) under special circumstances.

 

 

 

  3) For wet rock drilling, deep hole drilling should be accompanied by mandatory provisions for dust collection equipment.

 

 

 

  4) For on-site inspection and test projects, realistic reductions are made according to mandatory requirements and current national conditions in China.

 

 

 

  5) The blasting equipment processing and detonation methods, the provisions related to the fire detonator and the fuse are deleted, and the relevant contents of the electronic detonator are added.

 

 

 

  6) An electronic detonator detonation network and a hybrid detonation network have been added.

 

 

 

  7) Mechanized charge

 

 

 

  Mechanized charging is the main step in making significant progress in blasting operations. It not only guarantees the safety of charging, but also brings the direct benefit of increasing the amount of extended charge and reducing the ultra-deep. Compared with the filling of water in deep water holes, The mechanized charge can drain the water in the hole to make the emulsion explosive adhere to the wall, increase the charge, and the blasting quality is better than the blasting of the pulverized material. The rough statistic of the annual blasting in China is more than 100 million m, of which the water hole accounts for 1/3. About 30 million m or so on the left and right, after the mechanized charging, under the premise of the average unit consumption, the hole network can be enlarged by more than 20%, that is, the number of holes drilled by more than 20% is less than 6 million m. Above, the benefits of energy saving and consumption reduction can be seen.

 

 

 

  Therefore, this standard revision supplements the contents of the mechanized charge, and the relevant provisions of the mechanized charge scattered in the open-air blasting and underground blasting, and the detonation contents of the bottom of the compressed charge are all concentrated in this section, and combined with 7 years to install. The advancement of pharmaceutical machinery and the use in China, a single section of the charging machinery (6.5.3), in order to promote the promotion of the use of charging machinery to ensure safety in practice. The regulations for the loading of mixed vehicles have changed from 13 to 16 and the contents have been added or deleted.

 

 

 

  8) A section of the charge for the removal of the pre-charged time should not exceed 7 days.

 

 

 

  9) The post-explosion inspection content increased the safety of public facilities, buildings and structures, increased the regulations of inspectors, and refined the provisions for the inspection and discovery of problems.

 

 

 

  10) The treatment of blind cannons increases the rules for how blind cannons are handled.

 

 

 

  11) In the section on blasting effect monitoring, the lessons learned from frequent blasting accidents in recent years have been added, and the monitoring project has added “a source of danger that may cause secondary disasters”.

 

 

 

  12) Added a summary of the role of safety assessment and safety supervision in the blast summary section.

 

 

 

  7. Open blasting

 

 

 

  This chapter is compiled from the original regulation 5.1 (open-air blasting) 5.2 (chamber blasting). The major modifications are:

 

 

 

  1) It is strictly prohibited in the general regulations to use bare blasting in the open air.

 

 

 

  2) The deep-hole blasting provisions have added the contents of high-step blasting and air-space blasting introduced and developed in recent years.

 

 

 

  3) Based on the improvement of drilling machine operation accuracy and the improvement of management level, the acceptance criteria for deep hole blasting drilling are adjusted: the hole depth error is adjusted from ±0.5 to ±0.2m, and the inter-row spacing is adjusted from 0.3m to 0.2m. The borehole skewness is adjusted from 2.6% (1°30') to 2%. This kind of adjustment is relatively easy to make. There is a huge economic benefit hidden behind this adjustment: according to the current step blasting design software RK design program widely used in China, the preliminary estimation of the accuracy of the data is entered into the program after the blasting quality. Under the premise of the constant application of the metered rice, the pore network can be increased, and the amount of blasting can be increased by about 10%, which means that the average unit consumption is reduced by 10% and the amount of drilling is reduced by 10%. Each year, the drilling of medium and deep hole blasting is 100 million meters, and the calculation of 1.5 million tons of medicine can reduce the length of drilling holes of 10 million meters per year and save more than 10 million tons of explosives. This is a typical example of the benefits to technology and the benefits to management. Engineering practice also proves its feasibility and correctness. This is also a highlight of this revision of the procedure.

 

 

 

  4) Due to poor operating conditions in the chamber blasting, the initial investment is high, and the average unit consumption is high, and the accident rate is also high. In modern China where drilling machinery is popular, its practicality has become less important. And the scope of application is getting narrower and narrower, and the scale of blasting is getting smaller and smaller. At the time of this revision, our main idea is not to advocate or oppose, but some restrictions must be imposed.

 

 

 

  The 1 room blasting section removed some of the content and general provisions that were biased towards the operating rules, and reduced the length by half while maintaining the integrity of the process.

 

 

 

  2 It is stipulated that the blasting operation unit and the blasting technician must have the blasting performance of the same level or above (including the same level) in order to bear the design, construction, safety assessment and safety supervision of the corresponding class blasting.

 

 

 

  5) When the drilling and blasting process develops to today's level, the relatively backward process of medicine pot, snake hole blasting, etc., is no longer mentioned in the new standard, and naturally withdraws from the historical stage.

 

 

 

  6) The integration, reorganization, deletion and deletion of the provisions, such as:

 

 

 

  1 Comprehensive hydropower project and nuclear island project's protective layer excavation experience, compiled the provisions of Section 7.6, and standardized the protective layer excavation process.

 

 

 

  2 Deleted the relevant provisions on the field of mixed explosives.

 

 

 

  3 Move the frozen soil blasting of the original special blasting chapter to this chapter.

 

 

 

  8. Underground blasting

 

 

 

  This chapter is basically the content of the original procedure 5.3 (underground blasting), made some adjustments, additions and deletions.

 

 

 

  1) Throughout the past few years, water leakage accidents have occurred frequently, causing major personnel and property losses, and a safety clause (8.1.9) for water permeable accidents has been added. It is mandatory to design a special blast when underground blasting is carried out in a permeable section. There are practical emergency plans.

 

 

 

  2) Gas outburst, water permeable, high temperature environment, accidents under bad geological conditions often cause group death and group injury, and cause some secondary accidents. On the basis of research and analysis of accident cases, a mandatory provision has been added (8.1.7 ), it is required to stop the blasting operation immediately when the above-mentioned accidents occur, and study the safety plan and treatment measures.

 

 

 

  3) The transportation, hydropower, railway and other departments have a large amount of infrastructure projects each year, which is an important branch of the blasting project. The large-section tunnel excavation has its own characteristics and special technical requirements in the safety work, and the professional comrades of the relevant departments. After the study, the section “Tunnel Excavation Blasting” was added.

 

 

 

  4) Move all the high temperature blasting to Chapter 9, and move the blasting blast to this chapter as Section 8.12.14.

 

 

 

  9. High temperature blasting

 

 

 

  In recent years, with the increase of high-temperature mining area resource development projects, the blasting workload in the fire area has increased greatly, and many accidents have occurred. Some experiences have accumulated and many lessons have been learned. In the long run, the development project of high-temperature mining areas will continue and expand, and some fire-fighting and blasting projects for emergency resources will be launched one after another. In order to ensure the safety of blasting operations in high-temperature areas, we will digest and digest and improve the technology and management measures that have been expanded over the years. On the basis of this, with reference to some large-scale high-temperature mine site rules and regulations, combined with the original standard 5.3.8 (high temperature and high sulfur mine blasting) and 5.6.3 (high temperature hot condensate blasting), the mandatory provisions of this chapter are formulated to ensure high temperature blasting. Safety, this chapter has 9 sections:

 

 

 

  9.1 General regulations

 

 

 

  Provisions for common problems in high-temperature environments, including personnel, equipment, temperature measurement requirements, charge sequence regulations, and regulations for the evacuation of accident-seeking personnel.

 

 

 

  9.2 High temperature rock blasting

 

 

 

  This section is aimed at the safety of open-air deep-hole blasting in the stripping project near the fire area of ​​open-pit coal mines. According to the information on the site and the accident data, the mandatory provisions for charge preparation, cooling measures, temperature measurement safety and blasting process are mandatory. .

 

 

 

  9.3 High temperature and high sulfur mine blasting

 

 

 

  There are five aspects to the dangers of high temperature and high sulfur mines.

 

 

 

  1) The high temperature can cause the blasting equipment to explode and burn early;

 

 

 

  2) The chemical reaction occurs between the explosive and the high-sulfur ore, causing combustion and explosion;

 

 

 

  3) Ammonium nitrate, divalent iron ions, water reach a certain ratio, chemical reaction occurs when mixing, resulting in local temperature rise, causing early explosion of ammonium nitrate-containing explosives;

 

 

 

  4) Sulfur dust has an explosion hazard;

 

 

 

  5) High sulfur mines are at risk of spontaneous combustion.

 

 

 

  This section has mandatory provisions for these risk factors, applicable to open pit mines, as well as to underground mines.

 

 

 

  9.4 Blasting of thermocoagulated structures

 

 

 

  Mainly for furnace blasting, characterized by small scale, high ambient temperature and many equipment. This section is still the original 5.6.3 provisions, with a small amount of text modification.

 

 

 

  10. Underwater blasting

 

 

 

  On the basis of Section 5.5 of the original procedure, some adjustments and modifications have been made in combination with technological advances in recent years:

 

 

 

  1) In the "General Provisions", some contents belonging to the operational details have been deleted, and some successful experiences gained in recent years have been absorbed, combined with the special problems brought about by the special environment of "water", the navigation channel, the ship, and the water state. The unsafe factors in water blasting, the damaging effects of water shock waves and swells, the common contents of blasting equipment and detonating network used in water environment have been sorted and summarized. Compared with the original standard, this part is more smooth.

 

 

 

  2) The effect of underwater bare pack blasting is limited, but it is not prohibited.

 

 

 

  3) Underwater drilling and blasting is the core content of this chapter. In the past ten years, the number of drilling vessels has soared, and the amount of underwater drilling operations has also been increased. Many useful experiences have been accumulated in the project, and some accidents have occurred. Section 10.3 (underwater drilling and blasting) sublimates these experiences and educations into the content of mandatory provisions, and makes necessary modifications, additions and deletions to the original standard provisions.

 

 

 

  4) The rock plug blasting has not been much in recent years and has a tendency to decrease year by year. This revision has made a lot of deletions and reductions to the original 5.5.4 (underwater rock blasting), and the amount of text has been reduced by nearly half.

 

 

 

  5) Change the name of the original standard 5.5.7 (soft-base treatment blasting) to “explosive squeezing and compaction” (10.6). In these years, there are many silt-sludged and compacted projects. After more than 20 years of development and development, A complete set of unique new technology, a complete set of operating specifications. This revision will take its essence and incorporate it into the article, which will certainly benefit the operational safety and technological progress of the submerged dredging and compaction project.

 

 

 

  6) The original 5.5.8 (maritime rescue and wreck treatment blasting) was renamed as submersible blasting and underwater structure demolition blasting. The content changed little and only text modification was made.

 

 

 

  7) Move the original 5.5.6 (camp, dam and retaining rock blasting) from this chapter to Chapter 11 (demolition blasting).

 

 

 

  8) The ice-breaking blast removes the provisions of the reef under the ice, because such operations have basically not been done.

 

 

 

  11. Demolition blasting and shallow hole blasting in town

 

 

 

  With the large-scale construction of urban construction projects, a large number of buildings (structures) need to be demolished every year in China, and a large number of urban stone shallow hole blasting is used for trenching and field leveling, in the long-term, large-scale engineering practice. It has accumulated a lot of experience and opened up many new technologies and new technical fields, making China's demolition blasting engineering in the world's advanced level in terms of quantity, difficulty, design and construction. The revision work of this chapter is based on the original standard 5.4. It incorporates the experience and lessons of recent years, and is reprocessed and improved. No matter the old provisions or the new provisions, they have the characteristics of China and are close to the national conditions. Strong practical value. Compared with the original standard, there are the following important changes:

 

 

 

  1) According to the actual difficulties, it is clearly stipulated that the A, B, C, and D-level projects can combine the technical design with the construction organization design, making the design work more convenient and effective.

 

 

 

  2) Summarize the past practical experience, emphasizing the impact of landing spatter and landing pre-shoot on safety, affirming the shock absorption and anti-shock effect of trenches and buffer banks.

 

 

 

  3) The demolition and blasting of cofferdams, dams and rock ridges was moved to this chapter, and the text was revised to increase the provisions for water safety management.

 

 

 

  4) It is stipulated that the conditions for not experiencing the test explosion are of great significance for ensuring safe and simple construction procedures.

 

 

 

  5) In recent years, two major accidents have occurred in the blasting industry that caused shocks. The famous blasting experts were sentenced for this. The new standards were compiled and studied. After the lessons were learned, the section was dismantled and the pre-demolition was added. Mandatory provisions to ensure safety when dismantling.

 

 

 

  6) Newly added post-explosion inspection, a section of blind cannon treatment, which stipulates the treatment methods for inspection and discovery of major problems and the tracking of clearing operations.

 

 

 

  7) According to the successful practice of foundation pit support to retaining hole charge blasting and the experience of reserved charge hole and hole blasting in the Three Gorges cofferdam, the provisions for pre-buried pipe and blasting of drug retention room have been added.

 

 

 

  12. Special blasting

 

 

 

  This chapter is based on the provisions of Sections 5.6 to 5.9 of the original standard, combined with the new technologies and new processes developed in the field of special blasting in recent years, re-integrated and revised. Due to the rapid development of the special blasting industry in recent years, many large and medium-sized enterprises with an annual output value of several hundred million yuan have developed new technologies, processes and management models. Therefore, some new contents have been added during the revision, which has increased the space. .

 

 

 

  In the revision, it is divided into four sections according to the different explosive receptors and blasting process. The first section accounts for half of the space, which is for metal materials. The third section accounts for 40% of the space. It is for the oil and gas well blasting process, Section 2 The content is seismic exploration and blasting, and the fourth section is the drilling and blasting, which is clear and easy to find.

 

 

 

  12.1 Metal crushing and explosion processing

 

 

 

  Compared with the original standard, the length increased by 3%, mainly increased in the two sections of the energy-cutting blasting and explosion compounding. The main changes, additions and deletions are:

 

 

 

  1) With reference to the “Measures for the Safety Management of Blasting Operations” of the Ministry of Public Security, the procedures for applying for approval for special blasting operations units have been revised;

 

 

 

  2) With the technological advancement of the detonation method, the “explosion processing should use electric power to detonate” regulations is eliminated, and the company can choose the detonation method by itself.

 

 

 

  3) The provisions for the blast pit not to be used for destruction operations have been removed.

 

 

 

  4) Added “Gathering Cutting Blasting” to replace the original “Recycling and Cutting Blasting”, which increased the text by 5 times. In recent years, the energy-cutting blasting has been mainly applied to ship-breaking to the use of cutters for various cutting and even demolition blasting. This section combines the experience of various cutting processes and upgrades into safety regulations.

 

 

 

  5) Explosive composite single column for a small section

 

 

 

  Because explosive compounding is only a process in the field of explosive processing, there are only a hundred words in the original standard, which are clipped in section 5.6.5. This revision has been expanded to more than 400 words. In the blasting engineering classification table, the explosion complex is awesome. Among them, the implementation of grading management like rock blasting and demolition blasting seems to have three pillars. This is the inevitable result of the rapid development of the branch industry in recent years, rapid advancement in technology and technology. Of course, explosive compounding has become the largest, most powerful and most profitable leading enterprise in the special blasting industry. A large number of large and medium-sized processing plants with standardized management, safe production and hundreds of millions of output value have emerged. Well, there have also been a number of small processing factories or small workshops with no professional talents, no safety guarantee system, backward technology and poor product quality. Many safety accidents and quality accidents have occurred, disrupting the market and ruining the reputation of the industry. In response to this reality, the provisions of this section have made some mandatory provisions, requiring enterprises to be equipped with professionals and production facilities for the deployment of special explosives, and stipulate stricter operational safety requirements and site requirements, etc., with the aim of ensuring safety. When the mandatory requirements are met, the existing mixed state of Liangzhu is effectively rectified.

 

 

 

  6) The original standard 5.6.5~5.6.8, except for the combination of explosive composite and explosive crimping, was reorganized and text modified.

 

 

 

  7) Supplementary provisions for the explosion relief stress, joined to the explosion pressure, listed as subsection 12.1.6. The reason for the combination is that both of them are bare blasting, and the blasting has certain comparability to the environmental impact, and the safety requirements are similar.

 

 

 

  12.2 Seismic exploration and blasting

 

 

 

  Seismic exploration blasting is the only branch that uses the seismic waves generated by blasting to carry out beneficial activities. In other blasting operations, seismic waves are useless and harmful energy consumption. Various methods are needed to weaken the seismic waves and control their harmful effects. Seismic exploration and blasting is the use of blasting as a source of vibration. By observing the distortion of the seismic wave during the propagation process, it is inferred that the geological structure, size, shape and location of the reflection and refraction are obtained, thus obtaining the aquifer, oil and gas geological structure, ore-bearing. Useful information such as structures, faults and caves.

 

 

 

  This section was revised from the original procedure 5.7, revised in the text, deleted the provisions of the work details, the original 20 provisions were revised into six, but still maintain the smoothness of the original standard provisions.

 

 

 

  12.3 Oil and gas well blasting

 

 

 

  Oil and gas well blasting is an important branch of special blasting. It creates great economic benefits for the country every year. There is a strong professional team in the field, working hard in remote areas to support the booming development of this industry.

 

 

 

  During the revision process of the “Discussion Draft”, many revisions were received and a complete draft of the revision was improved to the revision team. After careful study, it was considered:

 

 

 

  1) The original provisions have played a significant role in the years of implementation. So far, no erroneous regulations that are not conducive to operational safety and enterprise development have been found. They still have practical significance and are deeply rooted in the hearts of the people.

 

 

 

  2) The overall revision is biased towards the operational details and is not subject to the requirements of the full specification. Therefore, the provisions of this section have not been substantially changed, and only partial modifications have been made on the basis of maintaining the original provisions.

 

 

 

  12.4 Drilling and Thunder

 

 

 

  In the revision stage of the “Discussion Draft”, it was proposed to delete this section. After research and discussion, it is believed that there are still many applications in this process. The overall content of the article is retained, and some fine regulations have been deleted, and the text has been reduced by half.

 

 

 

  13. Safety allowable distance and control of environmental impact

 

 

 

  The main content of this chapter is to stipulate the provisions of safety standards and environmental protection standards. In the event of civil disputes, criminal cases or claims accidents, the relevant provisions of this chapter are the basis for important judgments, so the content of this section is highly valued and applied at most. The provisions of this chapter are also an important basis for the safety design, the evaluation conclusions in the safety assessment, the preparation of supervision planning and construction safety management in the supervision work. Two points need to be specifically stated here:

 

 

 

  First, it is only legal to make safety design, safety assessment and safety supervision planning in accordance with the provisions of this section. The monitoring deployment and monitoring conclusions made in accordance with the provisions of this section are legally effective. Violating these regulations is illegal and major accidents occur. It is necessary to bear criminal responsibility.

 

 

 

  The second point to note is that these regulations are only basic and basic provisions. The data standards adopted are derived from statistical data. The boundary defined by the data is not absolutely bound to the accident, that is, outside the flying stone boundary. There is no absolute flying stone. There is no guarantee that there will be no damage to the building or facility due to blasting vibration. The probability is very small. Generally, a large amount of flying stones or inevitably will occur within the boundary. The damage of the building (construction) is only different in distance, and the probability of accidents is different. As long as the design boundary is made according to the standard, on-site blasting warning and evacuation according to the standard requirements, in case of an accident outside the boundary, it is non-responsible. In the event of an accident, the design and construction leaders and responsible personnel shall not bear criminal responsibility.

 

 

 

  Due to the importance and non-absoluteness of the standard, it is very difficult to modify each time. This revision, in addition to sorting out a large number of accident data at home and abroad in recent years to determine the standard, also refers to foreign regulations and standards. Relevant regulations have been carefully referenced and quoted according to the level of foreign standards, and try to be in line with international standards. The main revisions of this chapter are:

 

 

 

  1) Increased the qualifications of monitoring personnel and the reliability of monitoring instruments.

 

 

 

  2) After sorting the domestic and foreign materials, the experts' opinions were summarized and it was decided to introduce the vibration frequency in the blasting vibration safety allowable standard. The two symbiotic parameters of the frequency and the particle vibration velocity amplitude are used together as the main body of the blasting vibration. And to establish the blasting vibration allowable standards, in the revision also refer to some foreign national standards, the main additions and deletions and amendments are:

 

 

 

  1 According to the investigation and statistics of civil disputes over the years, the amplitude values ​​of the masses in the safety permit standards of various buildings have been slightly reduced, and the requirements have been appropriately raised;

 

 

 

  2 stipulates that the amplitude of the vibration velocity of the particle is the maximum of the three components of radial, tangential and heavy directions, and the vibration frequency is the main frequency of the amplitude corresponding to the amplitude;

 

 

 

  3 Newly given the frequency range of the hydropower station and power plant central control room equipment, hydraulic tunnel, traffic tunnel, mine roadway, newly poured large volume concrete allowed vibration velocity and the position of underground structure control point;

 

 

 

  4 Newly given the allowable vibration standard (frequency and amplitude) and control point position of the permanent rock slope;

 

 

 

  5 Newly given the allowable vibration standard corresponding to different age ranges and different frequency ranges of newly poured large volume concrete (C20);

 

 

 

  6 stipulates that the allowable standard for demolition blasting vibration should also consider the vibration of the building's falling ground;

 

 

 

  7 For the first time, the nuclear power plant and the protection object controlled by the inertial force of the earthquake were proposed, and the blasting vibration acceleration was allowed as the safety criterion.

 

 

 

  3) The normative provisions of the air shock wave are basically unchanged, and the overpressure value of the air shock wave of the operator in the shelter is indicated (the overpressure value of the location of the corpus callosum).

 

 

 

  4) Strengthened the noise control standard for blasting operations, selected the burst noise criterion as the control standard, and made provisions for noise monitoring and control. This section refers to foreign related materials and new regulations for low-frequency noise in China, and has achieved international standards. .

 

 

 

  5) The safety allowable distance of water shock waves and swells is listed separately. The relevant provisions have not changed much, and two new contents have been added:

 

 

 

  1 New safety control standards for the impact of water shock waves on fish;

 

 

 

  2 The safety standard for swelling is that the wave height does not exceed the calibrated water level of the dam and the reservoir, and does not inundate the shore protection object, and does not cause a collision.

 

 

 

  6) Individual flying objects to the personnel safety allowable distance table, deleted the content that is not closely related to China's national conditions and the relevant regulations for the elimination process, and the individual data were changed according to the provisions of the relevant provisions of this regulation.

 

 

 

  7) Move the internal and external safety distance of the blasting equipment library to Chapter 14.

 

 

 

  8) A number of serious blasting accidents have been caused against gas explosions and gas poisoning. In the revision of monitoring and control measures for gas and harmful gases, lessons have been learned in recent years, and relevant mandatory regulations have been added.

 

 

 

  9) Because the method of controlling the swell is immature, it is still necessary to experiment and explore in practice. This revision has deleted the content of swell control (deleting a small section).

 

 

 

  10) Due to the emergence of many electric detonators with special safety features, the electric detonator explosion area has been changed to “ordinary electric detonator explosion area”.

 

 

 

  14. Storage and safety management of blasting equipment

 

 

 

  At present, China has promulgated special regulations that are widely recognized by various departments and strictly enforce the safety management of blasting equipment warehouses and blasting equipment. In addition to the State Council’s Circular No. 466, “Regulations on the Safety Management of Civil Explosives” and this standard, there are also two national standards (both It has been the normative reference documents for this procedure, namely GB50089-2007 and GB50154-2009) and two documents of the Ministry of Public Security (GA837-2009, GA838-2009). Among them, GB50089-2007 is for the ground storage of production and distribution units of blasting equipment, GB10154-2009 for the earth storage and underground storage of the national material storage general warehouse; GB838-2009 for the blasting operation unit small blasting equipment warehouse stocks industrial explosives below 5t, Black gunpowder 2t or less, industrial detonator less than 20,000 hairs), GA837-2009 is the regulations for the security requirements of the warehouse, for all underground blasting equipment warehouses except the mine sub-library, this station is aimed at the blasting equipment use unit The storage and safety management of blasting equipment involves seven types of storage methods: ground storage, underground and earth-covering, underground storage and distribution stations, mobile storage, temporary storage, on-site temporary storage and mixed-use vehicles.

 

 

 

  As a management unit specification, it has always been based on the characteristics of the use unit (the warehouse usage period is not too long, the warehouse and the mine or the blasting operation point can not be too far away), and the regulations are looser in the internal and external distances of the warehouse. The warehouse is not suitable for major renovations and major changes, so for the past few decades, the initial regulations have been maintained. In recent years, with the wide application of mixed vehicles, the large and medium-sized explosives pools of some large and medium-sized mines have been greatly reduced. The newly opened mines are built or built on the ground according to the documents of the Ministry of Public Security and GB50089 and GB10154. According to these circumstances, many major editors of this revision proposed to unify the standards of the warehouses of the users and the production and business units and the national general warehouse. After research and discussion, they agreed that the timing of reunification is mature, and the unified standard is Practicable.

 

 

 

  On the basis of this cognition, the revision work of this chapter has been repeated several times. The final approved revision method is: it is necessary to repeat the original standard provisions with the normative references GB50089-2007 and GB50154-2009 of this regulation. The original standard provisions modified according to the reference documents are deleted from the detailed texts in this standard, only the implementation according to GB50089-2007 or in accordance with the relevant provisions of GB10154-2009; those who must mention or make provisions with GA837-2009 There are duplicate provisions in the content of GA838-2009. During the revision, the repetitive text is maintained or revised into simple, principled provisions to maintain the integrity of the procedure and the authority of the national standard, while providing the user with certain Convenience; the storage, transportation and management of blasting equipment that are not required by other units in the national standard (such as underground blasting equipment, warehouse, distribution station, various methods of transporting blasting equipment by unit, temporary blasting equipment) The library and temporary stacking at the site, etc., retain the original provisions or main contents during the revision.

 

 

 

  The important changes in this chapter are:

 

 

 

  1) The content is reorganized in the order of storage, transportation, and security management.

 

 

 

  2) Move the relevant internal and external safety distances of the original standard blasting equipment library (formerly 6.5, 6.6) to this chapter, simplifying the text, and keeping consistent with GB50089 and GB50154.

 

 

 

  3) The texts of the original standard provisions such as location, structure, facilities, lighting, communication, lightning protection, fire protection, etc. of the blasting equipment library are all deleted, and changed to GB50089 or GB50154;

 

 

 

  4) Added relevant contents of the movable warehouse, the mixed-car ground station and the relevant provisions of the small blasting equipment library.

 

 

 

  5) Safety management of blasting equipment.

 

 

 

  Five subsections of warehouse management, receiving and dispatching, inspection, destruction and reprocessing of the warehouse area were made. During the reorganization of the provisions, a large number of deletions were made, and only the systemicity, integrity and feasibility of the safety management work were maintained.
