摘　　要：针对具体的地质条件,以五沟煤矿F6断层为研究对象,结合研究区域内断层及底板灰岩水的空间分布关系,采用数值模拟及理论分析相结合的方法,对留设不同宽度煤柱时断层的突水危险性进行分析;利用理论计算确定F6断层未处理之前合理的煤柱留设宽度,同时考虑F6断层的三维地震探查成果及井下实揭资料,理论分析了下部含水层的注浆加固范围;综合理论计算及数值模拟计算结果对F6断层煤柱缩小的可行性进行研究,研究结果对于提高五沟煤矿煤炭资源采出率有着重要的意义。According to the specific geological conditions,taking F6 fault of Wugou Coal Mine as the research object,combined with the research of fault and the floor limestone water in the area of space distribution relationship,numerical simulation and theoretical analysis are used to analyze the water inrush risk of different widths of coal pillars,and theoretical calculation is used to determine the reasonable width of coal pillars before F6 fault treatment,at the same time,considering the ^(3D) seismic exploration results of F6 fault and the data of underground excavation,the grouting reinforcement range of the lower aquifer is analyzed theoretically.Combining the results of theoretical calculation and numerical simulation,the feasibility of reducing the coal pillar of F6 fault is studied.The research results have important significance for improving the recovery rate of coal resources in Wugou Coal Mine.
