瞬变电磁法在探测煤矿采空积水区中的应用

探测煤矿采空积水区通常较难，但可以充分利用瞬变电磁法对低阻地质体反应灵敏和分辨率高的特点，通过精细处理和分析研究，从而有效地探测采空积水区。本文介绍了瞬变电磁法的基本原理，阐述了瞬变电磁法在探测煤矿采空区中的应用，根据工作区域特有的物性地质条件，结合视电阻率断面图，分析视电阻率断面图，探测出煤矿采空区以及积水区的位置及范围。

Application of Transient Electromagnetic Method in Detecting Watermaccumulated Area in Coal Mine Gobs

Exploration of water--accumulated areas in mine gobs is generally more difficult, but people can fully utilize the characteristics of sensitive response and high resolution to low resistivity geological body that transient electromagnetic method has to make an effective detection on water--accumulated areas in mine gobs based on fine processing and analysis. This paper introduces the basic principle of the transient electromagnetic method and expounds the application of the transient electromagnetic method in detecting the coal mine gobs. According to the working area special property geological conditions and the analysis of apparent resistivity pseudosection obtained, the location and scope of coal mine gobs and water--accumulated areas in coal mine gobs are detected.
