摘 要:3022巷掘进过F5断层期间巷道顶板出现局部冒漏,形成两处高冒区,导致巷道原顶板支护失效现象严重,巷道掘进效率低。针对以上问题,对高冒区施工人工假顶,并在巷道内安装密集工字钢棚进行加强支护,实际应用效果表明:3022巷高冒区施工人工假顶并加强支护后,保证了高冒区顶板整体稳定性,控制了高冒区顶板冒漏现象,取得了显著应用成效。During the period of the 3022 roadway driving through F5 fault,local leakage occurred in roadway roof and two high caving areas were formed,which led to serious failure of roadway roof support and low roadway driving efficiency.In view of the above problems,the artificial false roof is constructed in the high caving area,and the dense I-steel shed is installed in the roadway to strengthen the support.the practical application results show that after the construction of artificial false roof and strengthening support in the high caving area of the 3022 roadway,the overall stability of the roof in the high caving area is ensured,the roof leakage phenomenon in the high caving area is controlled,and remarkable application results are achieved.
