摘　　要：区段平巷处于采掘工作的最前沿,经历采掘活动的多次扰动,围岩变形显著,支护难度较大,针对5201运输平巷的顶板控制问题,借助FLAC3D数值模拟软件,结合本矿巷道支护经验及矿压显现具体情况,确定5201运输平巷的基本支护原则及最终支护方案,经现场支护实践及持续矿压观测,证实了支护方案的有效性及合理性,实现了预期的安全效益及技术经济效益。The section drift is at the forefront of mining work.It has experienced multiple disturbances of mining activities,significant surrounding rock deformation and great support difficulty.Aiming at the roof control problem of 5201 transportation drift,the basic support principle and final support scheme of 5201 transportation drift are determined with the help of FLAC3 D numerical simulation software,combined with the roadway support experience and the specific situation of mine pressure.Through the field support practice and continuous ground pressure observation,the effectiveness and rationality of the support scheme are confirmed,and the expected safety benefits and technical and economic benefits are realized.
