Abstract

In this paper, under the geophysical prerequisite of low resistivity anomaly zone being the main characteristic of the goaf, researchers have used large fixed source loop transient electromagnetic method (referred to as TEM) to prospect the goaf in a coal mine of Shanxi Province. After a series of processing, the author writes a MATLAB program to calculate the all-time apparent resistivity, so researchers can map the all-time apparent resistivity profile and make the integrated interpretation or analysis. It is speculated that the south, northwest and northeast of the exploration zone have large goaf areas, and a smaller goaf is distributed in the center of the exploration zone. Party A should pay enough attention to these goaf areas and should make drilling verifications in time.
