在矿山作业的过程中,很重要的一部分工作就是如何破坏岩石和防止岩石的破坏。矿山作业使巷道围岩或露天矿坑边坡的平衡状态受到破坏,从而导致岩体有可能丧失稳定性,出现顶板冒落、巷道断面变形、采空区大片崩塌以及岩坡滑动等现象。研究岩体的破坏过程,分析它的规律和确定判别破坏的条件,对采矿工程的发展有很重要的现实意义。但是,由于岩体的复杂性,直到现时为止,还没有研究出普遍的分析岩体稳定的准则,工程实践上还不能够象 In mining operations, a very important part of the job is how to destroy the rock and prevent the destruction of the rock. The mine operation damaged the balance of roadway rock or open pit slope, resulting in the possibility of loss of stability of rock mass, roof caving, deformation of roadway section, large-scale collapse of goaf and slide of rock slope. Studying the failure process of rock mass, analyzing its regularity and determining the conditions of discriminating damage have very important practical significance for the development of mining engineering. However, due to the complexity of rock mass, until now, no universal criterion for rock mass stability analysis has been developed, and engineering can not yet be practically implemented
