摘　　要：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。以吉林某煤矿和山西某煤矿采空积水区探测为例,介绍了瞬变电磁法在探测煤矿采空积水区中的应用及效果。Exploration of water-accumulated areas in mine gobs is more difficult generally ,but we can fully utilize the characteristics of sensitive responsivity and high resolution to low resistivity geological body that the transient electromagnetic method has,to make an effective detection on water-accumulated areas in mine gobs based on fine processing and analysis. This article took the prospecting of water-accumulated areas in mine gobs in coal mines in Jilin Province and Shanxi Province as examples,introduced the application and effects of transient electromagnetic method in the exploration of water-accumulated areas in mine gobs.
