In order to understand the exploration detection capability of the transient electromagnetic method under some simple conditions, the authors conducted the physical simulation on the responses of the spherical anomalous body in different resistivity backgrounds, different forms of plate-like anomaly in the high resistance background, and spherical anomalous body at different depths. As a result, the authors obtained a number of induced voltage normalized curve profiles and apparent resistivity-time profiles, determined the best results of transient electromagnetic method for detecting the high resistance geological background conditions below the low resistance anomaly body, with the exploration depth being 2~3 times the side length of the frame. The results obtained by the authors provide some reference for the development of transient electromagnetic exploration.
