不同电法勘探方法在探测采空区等地质体中的比较

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。

Comparison of different methods of electrical prospecting in detecting geological anomalies such as goal

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.
