井下瞬变电磁勘探优缺点分析

摘要

中国煤炭产业的快速发展，对井下水灾害防治的要求越来越高。本文简要的介绍了目前主要应用于井下的几种物探方法，选择其中最常用的直流电法和瞬变电磁法进行了比较，并在山西某煤矿实验两种方法，分析了实验结果。最后对井下瞬变电磁勘探方法进行了总结。%The rapid development of chinese coal industry,with the increasingly high demand for underground water disaster prevention.This article briefly describes the several geophysical prosepecting methods is mainly used in underground,choose one of the most commonly used direct current electrical method and Time domain electromagnetic methods(TEM)were compared,and analyse of the experimental results of the two methods in a coal mine in Shanxi.Summarize of In-mine time domain electromagnetic methods finally.
