摘　　要：煤矿上下煤层间距过小容易增大下煤层支护作业难度,需要矿企结合实际环境升级回采巷道支护方案。A煤矿5~#煤层与上层4~#煤层的间距较小,且在采空区影响下,顶板易破碎,安全隐患高。为此,结合5~#煤层回采巷道支护现状进行数值模拟分析,研究采空区下的回采巷道支护参数。最后,验证了回采巷道支护方案有着良好的支护效果,可以应对5~#煤层顶板起伏大、强度低等挑战。Too small spacing between upper and lower coal seams in coal mines tends to increase the difficulty of support operation in lower coal seams,so it is necessary for mining enterprises to upgrade the support scheme of mining roadway combined with the actual environment.The spacing between 5#coal seam and the upper 4#coal seam in A Coal Mine is small,and under the influence of the goaf,the roof is easy to break and the safety hazard is high.Therefore,combined with the support status of the mining roadway of 5#coal seam,the numerical simulation analysis was carried out to study the mining roadway support parameters under the goaf.Finally,it was verified that the support scheme of mining roadway had good supporting effect,which can cope with the challenges of large fluctuation and low strength of 5#coal seam roof.
