摘要
针对大同四台矿14#煤层81005工作面回采巷道支护问题,从实际地质条件出发,进行了场论分析。研究了近距离煤层零内错回采巷道围岩变形的影响因素,结合FLAC数值模拟,得出了较为合理的巷道支护方案,以工业性实验进行了验证,取得了较好的成果,为确定近距离煤层零内错回采巷道支护方案的选择提供了强有力的支撑手段。
Supporting roadway for the 14^#81005 coal face in Sitai coal mine of Datong, starting from the actual geological conditions, then analysis field theory. Study the factors affecting surrounding rock deformation situation about close coal seams, combined with numerical simulation FLAC, come to the supporting program more reasonable solutions and industrial experiments were verified, and achieved better results to determine distance seam roadway supporting program chosen to provide a strong support tool.
