地球物理探测技术在采空区勘查中的应用

Application of Geophysical Probing Technique in Goaf Exploration

以山西开元矿为工程勘探背景,利用瞬变电磁法和氡气测量相结合的综合地球物理物探方法,对该矿采空区的分布情况进行了有效探测。分析了活性炭测氡法和瞬变电磁法探测技术的原理及特点,探讨了其探测方案,并对探测结果进行了对比分析,研究内容可为其他矿井地下采空区探测提供一定的借鉴。

Taking Shanxi Kaiyuan Mine as the background of engineering exploration,this paper used the integrated geophysical exploration method of transient electromagnetic method combining with radon surveying to effectively detect the distribution of goaf in this mine.This paper analyzed the principle and characteristics of active carbon measuring Rn technique and TEM detection technology,discussed their detection schemes and made comparative analysis of the detection results.The research content can provide certain reference for other underground goaf detection.
