摘 要:利用锚杆锚索附加金属网进行联合支护的方式对孤岛工作面内错尾巷进行支护优化设计,并对支护后的尾巷围岩变形情况进行监测。通过强化支护后,巷道围岩变形情况得到有效缓解,可以确保完成工作面的安全高效回采任务,减少了巷道维护开支以及露顶片帮事故的发生,提高了工作面回采效率。Anchor rod and anchor cable with metal mesh were used to optimize the support design of the wrong end lane in the isolated working face,and the deformation of the surrounding rock of the end lane was monitored after the support.After strengthening the support,the deformation of the surrounding rock of the tailrace was effectively relieved,which ensured the safe and efficient recovery of the working face,reduced the maintenance expenses of the roadway and the occurrence of open top and flaky gang accidents,and improved the recovery efficiency of the working face.
