炮孔爆破中残孔长度与夹制作用浅析

Simple Anylysis on the Length of Remains of Hole and Action of Clipping

本文对不同界面炮孔爆破形成的残孔形式、长度及有限界面边界“截止”爆破能量与残孔长度的关系、围岩围压应力对残孔的影响和夹制作用等有关问题作了分析。

In this actile the hole blasting with different boundary surface resuting in different length and form of hole remains, as wellas the action of blasting energy stopping in limited surface, the effect of initial pressure in rock on hole remains and the action of clipping are explained.
