Based on complex geological condition and multiple water inrush accidents in Fangezhuang Mine, water outburst channel mainly are dotted and vertical water conductive structures, water inrush area focused on Tatuo synclinal area in northern coalfield, 2022 working face of Fangezhuang Mine was taken as example, transient electromagnetic, audiovisual and radio wave pits technology were adopted to detect water - rich and concealed structures development, in the abnormal area with drilling technology. The result showed that the exploring area with invisible guide water structure, working face water-resisting layer was broken, recovering mining with water inrush risk.
