近几年来,随着矿井物探技术的发展和提高,矿井瞬变电磁技术在矿井岩层的探测方面发挥越来越重要的作用,由于采用小线圈测量,降低体积效应的影响,提高勘探分辨率,特别是横向分辨率,另外,井下测量装置距离异常体更近,大大提高测量信号的信噪比。
In recent years, with the development and improvement of geophysical prospecting technology, mine transient electromagnetic technology plays more and more important role in the detection of mine rock strata. Due to the small coil measurement, the influence of volume effect and the improvement of exploration resolution, Especially horizontal resolution. In addition, the downhole measuring device is closer to the anomalous body, greatly improving the signal-to-noise ratio of the measured signal.
