摘要
深孔卸压爆破在治理冲击地压中的作用得到采矿工作者的认可,通过浅析爆破破岩原理,论证了爆破卸压的基本原理,并研究了深孔爆破卸压在防治冲击地压中的应用,最后对深孔爆破主要参数:炮孔直径、炮孔间距、炮孔深度、封孔长度等进行了确定和优化。
The effect of deep hole pressure release blasting on impact ground pressure treatment is accepted by miner.Through analysis of blasting rock-broken theory,the basic principle of blasting destressing was proved,applications of deep hole blasting destressing on impact ground pressure prevention was researched.The main parameters of deep hole blasting like borehole diameter,borehole spacing,hole depth,sealed borehole length and so on are confirmed and optimized.
