摘要
针对近距离煤层回采后底部煤层回采巷道稳定性问题,以6128工作面为研究对象,采用理论分析、数值模拟和现场观测综合研究方法,分析了其回采结束后下伏14 m处6127工作面轨道平巷的稳定性问题,并设计了巷道的支护形式,取得了显著地经济技术效果,为类似开采条件下的矿井提供了一定的借鉴意义。
Based on coal seam stability after close distance coal seam mining problem, 6128 working face was taken as the study object, theoretical analysis, numerical simulation and in-situ observation research methods were adopted, 6127 working face roadway stability under 14 m in the underlying after stopping problem was analyzed, the roadway supporting form was designed, which got economic and technical effect significantly, and provided the certain reference for similar mining coal mineunder the same condition.
