煤矿深孔爆破技术的应用

Discussion on the coal mine deep hole blasting technology

深孔爆破技术的突破,既是解决岩石内部爆破自由面的突破,也是解决爆破漏斗向纵深发展的课题。深孔爆破必须有两个以上的爆破自由面,一方面在炮眼孔外,一方面在岩石内部。

The deep hole blasting technology breakthroughs, in fact is to solve the internal blasting free surface breaking rock. But also solve the blasting funnel to the depth development project. Deep hole blasting with blasting free surface must be more than two, on the one hand the outer of hole, the other in the rock.
