Abstract: One of the research focus of geophysical exploration in coal mine is how to delineate the range of water and infer the water abundant area. TEM is a ideal detection method to solute the hydrogeological problems of mine and has the advantage of reflecting the low resistivity body sensitively. In this paper, we use logging data to demarcate horizon, to infer comprehensively the water abundance and the range of water abundant area according to the geophysical low resistance anomaly together with the lithology analysis and sand shale ratio parameters in the interpretation process. Examples show that the results are good.
