摘　　要：简要论述了采煤工作面单极—偶极直流电透视原理和解释方法。正演结果表明，垂直、平行单极—偶极两种方法均能有效地突出工作面顶、底板围岩的影响，而压制煤层的影响，为大水煤矿有的放矢地探测工作面顶、底板内的含水、导水构造提供了一种新方法。The principle and interpretation method of the monopole dipole DC penetration at working face are expounded briefly.The forward results indicate that both the vertical and parallel monopole dipole methods can stress the influences of roof and floor rocks at working face ,and suppress the influence of coal seam.It provides a new method to detect the water bearing and water flowing structures in roof and floor rocds at working face for the coal mine with large water yield.
