地面电法勘探在查找采空区积水的应用

Application of Surface Electrical Exploration in Searching Water Accumulation in Goaf

采用瞬变电磁法对勘探区进行面积性的扫面工作,确定异常区后,然后在异常区进行一定量的直流激电测深工作,进一步确定异常区的范围和性质,查明该测区内采空区积水,以达到对10+11号煤炭开采时,对附近水体进行超前预测的目的。

Transient electromagnetic method is used to sweep the exploration area in an area, determine the abnormal area, and then carry out a certain amount of direct current induced polarization sounding in the abnormal area, further determine the scope and nature of the abnormal area, and identify the goaf water in the survey area, so as to achieve the purpose of predicting the nearby water body in advance when mining 10+11 coal.
