摘　　要：为探究近距离煤层群的高效率开采路径,结合某煤矿的近距离煤层群的实际情况,从回采巷道布置、开采顺序和支护方案三个角度同时着手,对上行开采模式在近距离煤层群中的应用进行了较为详细的探讨。在此基础上,对本次建立的上行开采方案的相关指标进行现场测试分析,根据分析结果,为后续的方案优化提供建议,确保上行开采方案具有更高的可行性。In order to explore the efficient mining path of the close range coal seam group,combined with the actual situation of a certain coal mine's close range coal seam group,a detailed discussion was conducted on the application of the upward mining mode in the close range coal seam group from three perspectives:mining roadway layout,mining sequence,and support plan.On this basis,on-site testing and analysis of the relevant indicators of the established upstream mining plan will be conducted.Based on the analysis results,suggestions will be provided for subsequent optimization of the plan to ensure that the upstream mining plan has higher feasibility.
