摘要
针对耿村煤矿东区2-3煤轨道运输下山围岩破碎较为严重、围岩稳定性较差、巷道修复工程量大等问题,提出新的修护加固方案,对锚杆型号及间排距、锚索型号及间排距、围岩注浆加固等进行优化,解决了破碎围岩巷道变形量大、重复修复等问题,并为矿井破碎围岩巷道注浆加固提供一定的参考价值。
According to the problems that the surrounding rock is more serious fragmentation, the stability is poor, the roadway repair engineering quantity is large in Geng Cun Coal Mine East 2-3 coal rail transport diphead, the new repair reinforcement scheme was put forward, that the anchor models and inter row spacing, type of cable and row spacing, rock grouting and solid are optimized to solve the broken surrounding rock deformation of roadway, repeated repair problems, which provide a certain reference value for mine broken surrounding rock grouting reinforcement.
