one of coal mining main task is to detect geological mining area geological structure and the distribution of water (guide), 3 D seismic exploration was mainly used for detection of geological structure, and electrical prospecting was used to construct the aquosity detection. In order to explore the possibility of three-dimensional seismic exploration water-bearing structure, the method of wave impedance inversion of seismic data to extract water information was adopted, and combined with the actual seismic data inversion results and transient electromagnetic exploration results in the watershed, by comparing and analyzing them, the extraction of seismic data of the water rich information characteristics and the water enrichment area of the transient electromagnetic method measured were basically identical. Results showed that the seismic exploration technology in the detection of geological structure in terms of accuracy was higher, constructing water or not can be extracted by drilling logging data of calibration information to determine the wave impedance inversion, and qualitative explanation had certain feasibility for the water information, which provided a new direction and the development for seismic exploration technology.
