摘　　要：针对长平矿五盘区复用巷道变形严重、巷道无法正常使用等问题,以五盘区5302工作面为背景,通过地应力测试和围岩强度测试得到了五盘区工作面围岩地质力学参数,并对53022复用巷道进行了初始支护方案设计。现场应用表明,53022巷顶底移近量和巷帮移近量不大,锚杆受力较为稳定,有效地控制了巷道围岩变形。In view of the serious deformation of the reused roadway and the roadway can not be used normally in the fifth panel area of Changping Mine,taking the 5302 working face in the fifth panel area as the background,the geological and mechanical parameters of the surrounding rock of the fifth panel area working face are obtained through the crustal stress test and the strength test of the surrounding rock,and the initial support scheme is designed for the 53022 reused roadway.The on-site application shows that the displacement amount of the 53022 roadway roof and floor and the roadway side are not significant,and the anchor rod force is relatively stable,effectively controlling the deformation of the roadway surrounding rock.
