For most rock masses in the nature the mean value of RQD, rock quality percentage ( RQP) and rock quality risk ( RQR) can be read off from the rock quality description charts plotted in this paper.

对于自然界大部分岩体，可根据结构面间距统计参数，直接在本文得出的一系列岩石质量图上定出RQD平均值、岩石质量百分比（RQP）及岩石质量风险（RQR）。

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。
