Operation use: Place the gun hole at the specified position to shake once, the spacer automatically deflate and clamp.
First, the placement of gas spacers
1. Deep hole blasting in open pit mine blasting engineering;
2. If the diameter of the blasthole is above 90 mm and the deep hole is above 10 m, the bottom or middle spacing can be used, and the interval length is 15%~30% of the continuous column charge.
Second, the main role: J reduce the explosive unit consumption, shock absorption and waterproof, reduce the base; reduce the explosion pressure inside the blasthole, reduce or even avoid the impact rock crushing caused by the coupling charge, expand the range of the rupture zone, improve the explosive energy of explosives Effective utilization, thereby reducing the consumption of explosives. In addition, due to the increased position of the charge, the distribution of the explosion pressure in the borehole is more uniform along the axial direction of the blasthole, which can effectively overcome the base and reduce the blasting bulk rate, and create favorable conditions for subsequent processes such as shovel loading. Non-civilian, safe, energy-saving products.
