Guangxi Province China Resources Cement Mine Special BJQ150 Gas Spacer Bulk Wholesale

Scope of application:
1. Deep hole blasting in open-pit mine blasting projects
If the diameter of the blast hole is above millimeters and the diameter of the deep hole is above meters, bottom or middle intervals can be used. The interval length is a continuous columnar device. %~% of medicine.
2. The main function is to reduce the unit consumption of the blast, shock absorption and waterproofing, reduce the foundation, reduce the explosion pressure in the blast hole, use the uncoupled charging process to impact and crush the ore rock, expand the scope of the fracture zone, and improve the effective utilization of blast energy. Reduce ** unit consumption. save costs. Its working principle is as follows. **The shock wave generated by the explosion is reflected in the blast hole to generate a second strain wave, which causes the crack network around the blast hole to expand before the gas is pressurized. Although the gas pressure generated by the explosion will be reduced, under the repeated action of a series of aftershocks, the shock wave's action time on the rock will be doubled, which will increase the degree of rock fragmentation. . There are three types of air spacing technologies in cavity blasting: hole bottom spacing, middle spacing, top spacing, and uncoupled spacing. 3. Blasting effect and analysis After blasting, the pile-shaped loose surface ore blocks are relatively uniform and there are fewer large blocks. After blasting, the eyebrow lines are neat
