China Petroleum and Chemical Corporation East China Petroleum Bureau Sixth Geophysical Brigade in the geological exploration blasting in Niuchang Township, Liuzhi Special Zone, according to local residents, their houses were damaged in the blasting; China Petroleum and Chemical Corporation East China Petroleum Bureau In order to verify whether the damage of the house in Niuchang Township was caused by the blasting, the Six Geophysical Brigade decided to simulate the blasting situation of Niuchang Township of Liuzhi Special Zone in Anxin Village, Gaodian Township, Dafang County, and entrusted our company to blast vibration at the site. Test work; according to the previous loading records, the minimum charge for geological exploration blasting is 2kg, and the maximum charge is 6kg. For the measurement data is more reliable, this instrument uses a total of 4 instruments, according to the environmental situation of Niuchang Township. In combination with the local environment, a total of 12 measuring points were set up, and the amount of the drug was measured several times. The data was obtained in 33 groups, and the data acquisition rate was about 92%. The data not recorded by the recorder may be separated from the position of the sensor. Area distance and height difference are related.
Shots: 1 dose: 2kg data acquisition rate is 100%
