摘　　要：针对王坡煤矿3206孤岛工作面回采巷道支护困难的问题,采用理论计算及数值模拟的方法确定了回采巷道支护方案,并进行现场试验。对工作面3206回风巷围岩变形及顶板离层进行现场监测结果表明,巷道围岩整体变形量不大,且巷道顶板无明显离层现象,支护方案合理有效。Aiming at the gateway support difficulty in 3206 isolated island working face of Wangpo Colliery,the author presents the application of gateway support scheme through theoretical calculation and numerical at 3206 working face,whose on-site monitoring results of the surrounding rock deformation and roof separation show that the overall deformation of the surrounding rock of the roadway is not large with no obvious roof separation of the of the roadway.

关 键 词：孤岛工作面 回采巷道 锚网索联合支护 巷道变形监测
