瞬变电磁法在探测采空区中的应用

Application of Transient Electromagnetic Method in Detection of Goaf

摘要: 为了研究运用瞬变电磁法探测兼并重组整合矿井采空区的方法,在研究瞬变电磁法探测技术原理和对背景噪声进行调查的基础上,采用瞬变电磁法分别对通合2号煤层工业广场和生产区的采空区进行了探测研究。通过数据解释,结果表明,在工业广场存在3处采空破坏异常区,在生产区存在8处采空区。

Abstract: To study the method of using transient electromagnetic method to detect the goaf of the integrated mine, on the basis of studying the principle of transient electromagnetic method and investigating the background noise, the goaf in the industry square and the production area in Tonghe No.2 coal seam are detected by transient electromagnetic method, respectively. Through data interpretation, the results indicate that there are three broken regions of goaf in the industry square and eight broken regions of goaf in the production area.
