| 摘 要： | 基于复合顶板回采巷道围岩活动特点,采用动态设计方法,对复合顶板回采巷道进行了锚网梁索支护设计,并通过对巷道支护效果进行监测,认为:复合顶板回采巷道中采用锚网梁索联合支护是可行的,但是在采动影响剧烈阶段围岩变形大,需要进一步优化支护参数或进行二次支护,为类似条件下的锚网索支护设计提供了一定的参考。

| Abstract: | Dynamic designing method is adopted for designing parameters of bolting with wire mesh and cables based on surrounding rock characteristics of coal roadway with compound roof.Simultaneously,supporting effect is monitored.The results show that bolting with wire mesh and cables is feasible to support coal roadway with compound roof.But the deformation of surrounding rock is large in intense stage of mining influence.Supporting parameters are further optimized and secondary supporting are adopt in the stage.It provides scientific basis for other similar roadway with bolt-mesh-cable supporting. |
