摘　　要：电法勘探在探测小煤窑采空区、富水陷落柱等方面常用的方法有高密度电法、瞬变电磁法以及可控源音频大地电磁法,但是三种方法都有各自的优缺点,该文对三种方法在理论上的优缺点进行比较,从而得出针对不同地质条件应选择的合适的勘探方法,为电法勘探的实际应用提供借鉴和参考。When use the electrical prospecting to detect the mined - out area of the coal mine, water-rich areas such as the fall of column, the USUal methods are high - density electrical prospecting, TEM and CSAMT, but three methods have their own advantages and shortcomings, this article will compare the three methods in theory, so as to reach a conclusion that in different geological conditions should choose the appropriate methods of exploration. Then provide reference for the practical application.

关 键 词：瞬变电磁法 可控源音频大地电磁法 高密度电法 优缺点 采空区 陷落柱
