摘要
通过对石嘴山一矿38区+600 m轨道巷现场调查及表面收敛监测结果研究,并运用岩层层理滑移机理和断裂机理对围岩变形破坏进行分析,得出了围岩破坏机理,为深部开采中巷道的维护提供了科学依据。
According to investigation and monitoring of roadway in No. 1 coal mine of shizuishan,The failure mechanism of surrounding rocks is analysed by using shippage mechanism and rupture mechanism of rock cleats. The results provide some scientiffic evidences for roadway maintenance in deep mining.
