摘　　要：电磁波探测技术应用于井下工作面的探测过程中,经常遇到时延现象;而在数据的反演成图时,经常遇到等值线似椭圆状,上述现象经常影响到最终异常区的圈定。针对工作中遇到的问题,详细的介绍了井下坑透中的时延现象产生的原因,以及电磁波探测技术在井下布点的局限性,及其对异常区成图的影响。During the process of electromagnetic detection technology applied in underground working face detection, it often encoun- ters time delay phenomenon, and when the data inverts into a chart, it often encounters similar oval - shaped contour. The above phe- nomenons often affect the final delineation of anomalies. Aiming at the problems encountered in the work, this article detailedly de- scripted the causes of time delay phenomenon in underground penertration detection, as well as distribution limitation of electromagnetic detection technology applied in the underground, and the impact on abnormal area mapping.
