摘　　要：断层水害是煤层底板突水的主要类型之一。局部裂隙发育叠加采动扰动,为底板突水通道形成提供了重要条件。矿井直流电阻率法根据主动源多频率发射信号,可以获取适合全空间三维电阻率反演所需要的数据体。本文以孟家窑煤业21采区为例,分析了探测底板裂隙含水性的有效方法,利用全空间多频电阻探测与全空间电阻三维反演成像,为地质数据体的直观表达提供了支持。Fault water hazard is one of the main types of water inrush from coal seam floor.The development of local fractures and mining disturbances provide important conditions for the formation of water inrush channels in the floor floor.According to the multi-frequency transmission signal from the active source,the mine DC resistivity method can obtain the data body required for the full-space three-dimensional resistivity inversion.In this paper,taking Mengjiayao Coal Industry 21 mining area as an example,an effective method for detecting the water content of floor fractures is analyzed,and the full-space multi-frequency resistance detection and full-space resistance three-dimensional inversion imaging are used to provide support for the intuitive expression of geological data.
