摘要
目前,在煤炭开采的过程中底板突水时有发生,严重影响煤矿正常回采。针对底板异常区富水性的探测,一种基于三维瞬变电磁法可以弥补了传统勘探技术在矿井工作面底板探测富水范围的不足。本文以某煤矿7401工作面为研究区,通过两次三维瞬变电磁法对7401工作面底板进行探查,分析底板异常区视电阻率变化,验证底板异常区的注浆效果。
At present,in the process of coal mining,the bottom plate water outburst occurs from time to time,which seriously affects the normal mining of coal mines.For the detection of the water-rich area in the abnormal area,a 3D transient electromagnetic method can make up for the deficiency of the traditional exploration technology in detecting the water-rich range in the floor of the mine working face.In this paper,taking 7401 working face of a coal mine as the research area,the bottom plate of 7401 working face was explored by two 3D transient electromagnetic methods,analyzed the apparent resistivity change of the abnormal area,and verified the grouting effect of the abnormal area.
