摘　　要：为了解决安徽淮南朱集西矿13501工作面轨道顺槽受下方11-2煤层采动影响后顶板破碎、两帮内移量大等围岩变形问题,利用FLAC^(3D)数值模拟软件进行保护层开采模拟并进行支护方式优化。通过现场工业性试验,巷道围岩变形得到了有效控制,有效保证了矿井的安全高效生产,为同类型下的深井巷道支护提供借鉴。In order to solve the surrounding rock deformation problems such as broken roof and large internal displacement of the two sides affected by the mining of the lower 11-2 coal seam in the 13501 working face of Zhujixi Coal Mine,Huainan,Anhui Province,the protective layer mining was simulated and the support mode was optimized by using FLAC^(3D) numerical simulation software.Through the on-site industrial test,the surrounding rock deformation of the roadway has been effectively controlled,which effectively ensures the safe and efficient production of the mine,and provides a reference for the support of deep roadway under the same type.
