摘要
随着煤炭工业的迅速发展,由煤矿采空区引发的一系列灾害已成为危害矿山及社会安全的重要因素之一。为了消除安全隐患,对未知采空区的探测意义重大。简要介绍了瞬变电磁法的工作原理、探测采空区的地球物理前提及装置的选择,通过实例说明在砂岩工作区运用该方法对采空区进行探测,取得了良好的效果,应用前景广阔。
With the rapid development of the coal industry, a series of disaster caused by coal mine goal have become one of the important factors threatening coal mine and social safety. It has great significance to detect the unknown goal in order to eliminate the safety hidden dangers. The paper briefly introduced the working 15rinciple of transient electromagnetic method, the geophysical precondition in coal mine goal detection as well as device choice. Through the actual example, this paper expounds the application of this method in coal mine goal detection in sandstone area, has achieved obvious effect and has great application prospects,
