Abstract: The mine water gushing is one of the difficult problems puzzled the safety mining.The investigation of the hydrogeological condition of the working face is a prerequisite to control effectively the water hazard and guarantee the safety mining.The production practice in Feicheng Mining Bureau proved that the comprehensive geophysical survey in which the DC electrical survey,Rayleigh wave method and transient electromagnetic method are the main means,is a simple,high-speed and effective tool to detect the geological structure,water abundance of aquifer and concealed water flowing structure at the working face and the front of driving end.
