摘　　要：基于井下瞬变电磁法对某矿71309工作面底板含水性的探测结果,划分煤层底板岩层含水性分布异常区,结合实际地质条件,借助FLAC3D软件建立流固耦合数值计算模型,并对数值计算结果进行分析,结果表明:煤层底板受采动及承压水影响,底板破坏带与含水异常区对接,发生底板突水事故。研究结果为指导煤矿安全生产提供了参考依据。The abnormal distribution area of the coal seam floor aquosity was divided on the basis of the detection results with the transient electromagnetic method in 71309 working face of a mine,a fluid-solid coupling numerical calculation model was set up according to the actual geological conditions and by using FLAC3D software,and analysis was made on the results of the numerical calculation.The results indicated that since the seam floor was affected by the mining and confined water and the floor failure zone and water-bearing abnormal area butted,the floor water inrush accident might happen.The research results can provide a reference for the guidance of safe production in coal mines.
