Abstract: In order to roadway ahead of goaf water disaster occurrence and the occurrence of whether accurate azimuth detection, comprehensive advance detection in mine TEM and borehole induced polarization method is put forward, and introduces the technical principle and layout method of two methods, two kinds of geophysical methods were found to exist in front of mining goaf water, according to the detection results of drilling the design and construction of the front, and advance drainage of goaf water. The results show that the comprehensive exploration method of mine TEM and borehole induced polarization method can effectively detect the water content and the location of the goaf, and the results are accurate and reliable.
