中文摘要：
介绍了矿井瞬变电磁法超前探测在井下运用的基本原理、技术和方法。在数据采集过程中，通过调整天线的法线与巷道底板的夹角，探测巷道顶板、顺层和巷道底板方向上介质的电性变化情况。对采集到的数据进行畸变处理、深度校正后，绘制视电阻率等值线断面围。探测结果表明，该方法能准确罔定巷道迎头前方的地质异常并反映出异常体的空间特征，对解决巷道掘进迎头前方的地质异常是一种快捷、有效的勘查手段，可以为煤矿水害的预报和防治提供重要的技术依据。
英文摘要：
This paper introduces the advanced detecting of mine transient electromagnetic method used in the mine. In the process of data acquisition, the variation of electric properties of medium in the roadway roof, the bedding and the roadway floor were detected by adjusting the angle between the normal direction of the antenna and the roadway floor. Thei soline sections of apparent resistivity have been drawn after the collected data were processed in the distortion way and corrected in depth. The detection results show that the method can be used to locate the geological anomalies and find out the space characteristics of the anomalies. Therefore, it can be considered as a quick, effective exploration method to solve the geological anomalies in the direction of the head- on roadway excavation, which is important to predict and prevent coal mine flood.
