摘要
本文介绍了定向断裂控制爆破的几种常用而有效的方法,通过计算爆破冲击波作用下炮孔壁的环向拉应力和爆生气体压力来分析了定向断裂控制爆破的机理。介绍了部分种类岩石爆破的炮孔直径和药柱直径的合理取值。
Several unvarying and effective methods of directional fracture controlled blasting are introduced in this paper. Mechanism of directional fracture controlled blasting is analysed according to cal- culating of round tensile strength of shock wave and gaseous explosion product. R.ational result of hole diameter and charge diameter of segmental rock blasting is ingtroduced.
