摘要
基于地应力实测结果采用大型岩土类三维分析软件3D-FSM DDM间接边界元数值系统,分析了西部大采深巷道围岩应力演化及其变形破坏规律,并在深知西部大采深巷道围岩变形原因及其破坏根源的基础上,进一步探求高地应力条件下西部大采深巷道围岩稳定性控制对策。
Based on the results of mining stress measurement, the 3D-FSM DDM indirect boundary element numerical system is used to analyze the stress evolution and deformation and failure of the surrounding rock in the large mining depth roadway. This paper further explored the stability control measures of the surrounding rock in the western large mining depth roadway under the condition of high ground stress.
