摘要: 以霍州煤电A 煤矿为实验矿井,采用瞬变电磁技术和无线电波透视技术对煤层构造进行综合探测,并对物探
结果进行钻探验证。数据结果表明:在5-1011 巷距迎头75耀105 m范围内,煤层中大约20 m处存在一个陷落柱异常
体;在与开切眼水平距离52 m左右,发育深度为20 m(45耀65 m之间)的低电阻率区。钻探结果证实了物探结果的准
确性,为工作面安全回采提供了依据。

Abstract: Taking A Coal Mine of Huozhou Coal Electricity Group as an experimental mine, transient electromagnetic technology
and radio wave perspective technology were used to conduct comprehensive detection of coal seam structure, and drilling verification
on geophysical exploration results were carried out. The results showed that there was a subsided column abnormal body in
the coal seam about 20 m in the range of 75-105 m away from the heading of 5-1011 roadway; a low resistivity area with a depth
of 20 m (45-65 m) was developed at a horizontal distance of about 52 m from the open-off cut. The drilling results confirmed the
accuracy of geophysical exploration results and provided the basis for safe mining of working face.
