摘　　要：为保障新景煤矿15^(#)煤西翼轨道大巷围岩稳定,现场调研及矿压监测掌握其表面变形规律,采用FLAC^(3D)数值软件模拟分析大巷围岩破坏特征,提出针对性加固方案。结果表明:采用注浆锚杆、注浆锚索深浅联合注浆工艺进行加固,数值模拟表明其具有可行性,应用后大巷围岩变形量微小,加固效果良好。In order to ensure the stability of the surrounding rock of the west wing track main roadway of the 15^(#)coal in Xinjing Coal Mine,on-site research and mine pressure monitoring are conducted to grasp its surface deformation law.FLAC^(3D)numerical software is used to simulate and analyze the failure characteristics of the main roadway surrounding rock,and targeted reinforcement schemes are proposed.The results show that the combination grouting process of grouting anchor rod and grouting anchor cable depth and shallow is used for reinforcement,and numerical simulation shows its feasibility.After application,the deformation amount of the main roadway surrounding rock is tiny,and the reinforcement effect is good.
