微动探测法和高密度电法在广东某矿山地下空洞探测中的应用研究

Application of Fretting Exploration Technology and High-density Electrical Method to Goaf Detection of a Mine in Guangdong Province

随着矿产资源的不断开采,矿区地下产生了众多空洞,带来极大的安全隐患,必须加以治理,首先需要确定空洞的范围和埋深,而微动探测法和高密度电法均为探测地下空洞的常用方法。论文以广东某矿山地下空洞探测为例,通过对微动探测法和高密度电法数据的整理分析和对比解释,确定了工区基岩面的深度和岩溶引起的空洞,取得较好的实践效果,为该区域的治理提供了科学依据。

With the continuous mining of mineral resources,there are many goaf in the mining area,which bring great security risks.Therefore,it is necessary to determine the scope and buried depth of the goaf.Fretting Exploration technology and high-density electrical method are commonly used to detect goaf.Taking the goaf detection of a mine in Guangdong Province as an example,this paper analyzes and compares the data of fretting exploration and high-density electrical method to determine the depth of bedrock surface and the goaf caused by karst in the work area,and achieves good practical effect,which provides a scientific basis for the governance of the area.
