摘要
物探方法主要有电、磁、重、震、放射性等五种方法,煤矿井下物探使用最多的是电法。此文主要介绍在九龙矿通过采用瞬变电磁、无线电波坑道透视、电测深、幅频电透视等4种常用井下物探方法采集的一手数据,结合后期矿方对物探异常区钻探验证的结果,对不同物探方法参数界定的绝对值来判定是否存在真实异常区。
Geophysical exploration methods mainly included electrical,magnetic,gravity,seismic and radioactive methods.The most widely used geophysical exploration in coal mine is electrical method.This paper mainly introduced the first-hand data collected by four commonly used underground geophysical exploration methods in Jiulong Mine,including transient electromagnetic,radio wave tunnel perspective,electrical sounding and amplitude-frequency electrical perspective.Combined with the results of later drilling verification of geophysical anomaly areas by the mine,this paper studied whether the parameters of different geophysical exploration methods could define an absolute value,which could determine whether there was a real anomaly area.
