摘要
以长平煤矿为试验地点,采用瞬变电磁法对掘进巷道进行超前探测,研究分析煤岩体天然场、干扰背景场以及数据处理对探测结果的影响;确定探测有效距离,并根据探测距离对数据进行反演;总结出瞬变电磁法视电阻率变化特征,为后期探测工作提供了参考。
In Changping Mine, transient electromagnetic method was used in the advanced detection of driving roadways to study the natural field of coal-rock, disturbance background field, and effects of data processing on the detection results. The effective distance of the detection was determined and then it was used in inversion calculation of the data in order to conclude the variation of apparent resistivity of the transient electromagnetic method, which could be references for the future work.
