浅析平朔安太堡矿区采空区瞬变电磁异常特征

Analysis on the Transient Electromagnetic Anomalies in the Gobs of Antaibu Coal Mines in Pingshuo

应用瞬变电磁勘探方法对平朔煤矿采空区进行勘查,介绍了瞬变电磁法野外数据采集技术,并对采空区的瞬变电磁法视电阻率异常特征进行了分析,推断了采空区平面分布范围并经钻探验证。通过对瞬变电磁资料、地调资料、钻探资料综合解译,分析了平朔煤矿安太堡矿区不充水采空区瞬变电磁法呈现低电阻率异常特征的原因。

The paper explores the gobs of Pingshuo Coal Mines with the help of TEM,introduces the data collection technology of TEM,analyzes the transient electromagnetic anomalies in the gobs and deduces the plane distribution of gobs,proved by actual drilling.After interpreting the transient electromagnetic data,geological data and drilling data,the paper then analyzes the reasons for the low-resistance transient electromagnetic anomalies in the gobs without water in Antaibu Mines.
