中文摘要：

为控制受动压影响下的主煤仓及附近巷道的变形破坏,针对方山煤矿21040跨采工作面的围岩特性及煤仓的生产地质条件,采用FLAC（3D）数值计算软件模拟跨采面推进过程中与煤仓及巷道距离不同时围岩的位移规律。根据动压影响下巷道围岩变形规律,确定对主煤仓进行井圈加固及对附近巷道进行锚杆锚索加固。

英文摘要：

In order to control the deformation and failure of the main coal bunker andthe roadway,in view of the surrounding rock characteristics of the 21040 working face and the geological conditions of the coal bunker, using FLAC~（3D） value calculation software to simulate the different distances between the working face and the coal bunker, get the evolution process of the surrounding rock displacement.According to the roadway deformation law,determines the final support scheme.
