摘要
介绍了矿井瞬变电磁法及井下直流电法的工作原理及装置,通过两种方法在工作面顶板水和掘进前方采空区探测方面的应用案例,说明工作面顶板水探测方面瞬变电磁探测效果与已知水文地质资料基本吻合;掘进前方采空区探测时,两种勘探方法均取得了较好的效果。
The paper introduced the working principle and devices of mine transient electromagnetic method and underground direct current method.The application of two methods in detecting the roof water and the goaf in front of the tunneling face shows that the result of transient electromagnetic method in the roof water detection is basically consistent with the known hydrogeological data,and the good results of two methods were achieved in the detection of the goaf in front of the tunneling face.
