中文摘要：
近年来，煤矿水害问题一直是影响煤矿正常生产的难题，煤矿防治水工作和矿山水文地质工作已成为煤矿急需解决的问题．主要介绍的直流电法是为煤矿防治水工作提出指导性意见，通过布置在地面的所有电极对地层进行电阻率采集，进而在二维电阻率反演软件中得到二维电阻率断面图，较为直观的反应地下赋水情况，通过现场的实际的工作，圈定了导水裂隙带、采空区积水的范围，为煤矿防治水工作提供了准确信息．
英文摘要：
In recent years, water disaster in coal mines has always affected the normal production of coal mines. Mine water prevention and mine hydrogeology has become an urgent issue to be solved in coal mines. This paper mainly introduces the DC electrical method for mine water prevention and guidance. Through the arrangement of all the ground electrodes, it collects the resistivity. Then, in the 2D resistivity inversion software, it obtains the 2D resistivity section, which reflects the situation of underground water occurrence more intuitively. Through practical work, water flowing fractured zone and water range in goaf have been delineated, which provides accurate information for mine water prevention.
