In view of the frequent occurrence of water outburst accidents in coal mine goaf, due to the multi-solution problem of single geophysical prospecting method, it could not meet the needs of comprehensive prediction application. In this study, the comprehensive geophysical prospecting method was used to finely delineate the goaf and water accumulation range of coalfield. The comprehensive geophysical prospecting method fully integrated the advantages of seism and electrical prospecting. The two technical methods complemented each other and verified each other, which could accurately obtain the distribution range of coal mine goaf and water accumulation area in goaf, and provide accurate geophysical prospecting data for mine safety production.
