Research on the integrated geophysical detection of hydrogeological condition in mine working face

Based on the analysis of theoretical basis, technical characteristics and limitations of mine transient electromagnetic method(MTEM) and high density resistivity method, this paper proposed the integrated geophysical method to detect hydrogeological condition of mine working face by combining the above two methods. With the detection case in 121101 working face, this paper discussed the working procedure, data acquisition, processing and interpretation methods of integrated geophysical detection. Results of engineering application show that the integrated geophysical method can remedy the defect of mine transient electromagnetic method (unable to distinguish the abnormal responses of roof and floor) and contrast the detecting results of both methods, thus remove the false anomaly aroused by interference. The integrated geophysical method can effectively detect the hydrogeological condition of mine working face and provide technical support for safe mining.
