本文介绍勤俭煤矿层状岩层光面爆破的实践技术。根据光面爆破的原理,分别阐述了装药集中度、装药结构、孔距、不偶合系数、炮眼密集系数等相互关系,并按照岩石力学的理论分析了他们的应用条件。
This article introduces the practical technique of smooth blasting strata strata in the thrift coal mine. According to the principle of smooth blasting, the interrelationship between charge concentration, charge structure, hole distance, uncoupling coefficient, dense coefficient of blasthole and so on are respectively described. Their application conditions are analyzed according to the theory of rock mechanics.
