It was urgently necessary to probe its internal structure and moisture concealed roof and floor lithology changes, prevention of water inrush before stoping in mine. Using a single detection technology can not solve the complex problem of mine geology, mines in Handan Mining Group used TEM, pit through, high-density electrical sounding integrated geophysical techniques for underground coal seam perspective and roadway floor, ahead of the lateral detection and achieved good results, reaching the effective control of three-dimensional space.
