摘　　要：针对东曲矿8、9#近距离煤层,下部煤层回采巷道受到上部煤层采空区的影响,出现巷道围岩难控制的问题。以东曲矿19303工作面为研究背景,通过采用理论分析以及数值模拟的办法提出19303工作面顺槽的合理的支护方案并采用数值模拟进行验证。结合现场监测结果表明所选用的方案能够保证矿井安全生产的需要。For the close-distance coal seam of No.8 and No.9 in Dongqu Mine,the mining roadway in the lower coal seam is affected by the goaf of the upper coal seam,and there is a problem that the surrounding rock of the roadway is difficult to control.Taking the 19303 working face of Dongqu Mine as the research background,a reasonable support scheme for the 19303 working face is proposed by theoretical analysis and numerical simulation and verified by numerical simulation.Combined with on-site monitoring results,the selected solution can ensure the safe production of mines.
