摘要
本文通过套筒致裂法测试巷道围岩应力及力学性质，并以此进行围岩稳定性分析和分类；提出了巷道围岩稳定性判据以及巷道围岩分类的原则；介绍了本稳定性分析方法在若干煤矿巷道围岩及立井井壁应力测试地点的应用。
Author of this paper attempts to carry out surrounding rock classification through rock stress and rock behaviour measuremens by sleeve fracturing technique. In this paper surrounding rock stability criterian and rock classification principle are proposed and application of the rock stability analysis method to rock stress and shaft lining stress measurement in colliery is described.
