摘　　要：为了探究断层构造对工作面底板突水的影响机理,运用理论分析、物探与FLAC3D软件数值模拟等方法,对工作面底板富水性,开采过程中工作面应力、塑性破坏区等变化规律进行分析研究,得出断层的存在缩短了突水路径,增加了底板含水层承压水导升高度,增加了工作面突水的危险性。研究结论为更好地开展矿山防治水工作提供了理论支撑,对其他矿山防治水工作具有重要借鉴意义。In order to analyze the influence mechanism of the fault structure on the inrush of the bottom plate of the working face,through theoretical analysis and numerical simulation of FLAC3 D software,analyzed and studied the variation rules of water-rich working face floor,working face stress,plastic failure zone,and obtained the influence law of fault structure on water inrush of working face:the existence of fault shortened the water inrush path,increased the height of confined water of floor aquifer,and increased the outburst risk of working face.The research results provide theoretical support for better water control in mines and have important reference significance for other mine water control work.
