摘要
煤炭资源开采破坏了矿山生态环境,造成了多种地质灾害,探明煤矿开采造成的采空区范围及具体位置对采空区治理至关重要。针对这一问题,介绍了综合电法在探测煤矿采空区中的应用,首先介绍了采空区的电性特征,选用中间梯度法、电测深法及高密度电法相结合,分析各类图件,按照曲线形态进行分区,再结合地质条件进行综合划分,圈定了2个主要的采空区和1个次要采空区,3个采空区都在村庄保护煤柱线之内。实践表明,综合电法勘探对采空区的位置及范围探测有较好的效果。
The coal resources mining destroys the ecological environment and causes a variety of geological disasters, the location of the goaf is important. Based on this problem, the application of integrated electrical method detecting goaf was introduced, the electrical characteristic of the goaf were introduced, combined with middle gradient method, electric sounding method and high density resistivity method, the exploration areas were zoned based on curves shape by analyzing various maps and drawings, combined with geological condition, two main goaf, one minor goaf, three goaf were all inside of the protection coal column line. The practice showed that comprehensive electrical exploration exerted good effect on detection of goaf location.
