摘 要:为确保15#煤西三盘区水仓超高巷道围岩控制效果,针对软弱易泥化围岩控制过程中存在的问题,提出采用高强锚杆+锚索+底板注浆+表层喷浆方式对围岩进行控制。支护方案现场应用后,超高巷道顶板、两帮、底鼓量最大分别为15 mm、30 mm、21 mm,有效解决了易泥化围岩超高巷道围岩控制难题,取得显著应用成果。In order to ensure the surrounding rock control effect of super-high roadway in water bin of the 15#coal west third panel area,aiming at the problems existing in the control process of weak and easy argillization surrounding rock,the method of high-strength bolt+anchor cable+floor grouting+surface grouting is proposed to control the surrounding rock.After field application of support scheme,the maximum amount of roof,two sides and floor heave of super-high roadway is 15 mm,30 mm and 21 mm respectively,which effectively solves the problem of surrounding rock control of super-high roadway with easy argillization and achieves remarkable application results.
