Abstract

In order to improve the accuracy of mine transient electromagnetic(MTEM) detection results we carried out field detection experiments for the underground metal interference (tunneling machine, bolt and the anchor net),by analyzing the effects of interference, it turns out that these metallic facilities could produce strong transient electromagnetic response, there are some disciplinarians about metal interference in the transient electromagnetic response, the effect of interference is greater in the later period. We applied metal interference correction method based on fitting function for date processing, impaired and eliminated the low resistance false local anomaly, and the correction method improved the accuracy of results interpretation. The practical application shows that the tunneling machine has the most influential on the results of detection, the anchor net takes second place, minimum the bolt has.
