摘　　要：针对长平矿53082复用巷道,其围岩稳定性差,受工作面二次采动应力影响,巷道极易变形破坏等问题,通过围岩地应力测试、强度测试和钻孔窥视等方法获取巷道围岩地质力学参数,拟定了该巷道支护方案;新支护方案应用表明,巷道顶底移近量和巷帮移近量不大,锚杆受力较为稳定,有效保障了巷道的二次复用。Aiming at the poor stability of the surrounding rock and the high risk of deformation and damage in the 53082 reuse roadway of Changping Colliery,the geological and mechanical parameters of the roadway surrounding rock are obtained through methods such as rock stress testing,strength testing,and drilling observation,and a support plan for the roadway is also formulated,whose application shows that the convergence of the roof and floor of the tunnel and laneway's side are not significant,and the bolt force is relatively stable,effectively ensuring the secondary reuse of the tunnel.
