采用KS—1型应力计和钻屑法检测门头沟矿二槽壁式刀柱工作面的爆破卸载效果,获得了增压区和减压区,有效影响范围和时间。爆破工艺等时空参数。使爆破卸载这一防治冲击地压的常规而又有效的措施得到定量化研究。
The KS-1 stress gauge and drill cuttings method were used to detect the blasting unloading effect of the work surface of the two-slotted wall pillars in Mentougou Mine. The supercharging zone and decompression zone were obtained, which effectively affected the scope and time. Blasting and other space-time parameters. So that blasting unload the prevention and control of the impact of the conventional and effective measures to get a quantitative study.
