According to the basic principles of Bieniawski's geotechnics rock classification, a classification of stope stability is established on the basis of five parameters, i.e. unia-xial compressive strength, RQD, joint spacing, joint state and underground water conditions.

本文根据Bieniawski的地质力学岩体分类法的基本原理，基于岩石的单轴抗压强度、RQD、节理间距、节理状态和地下水条件等五个参数，定出一种采场稳定性分类方法。
