Abstract: The aquiferous gob had been formed when the gob ,which shaped during coal mining, being filled with water. The disaster of water inrush caused by it is more higher in the proportion of the major accident of the coal mine this years, especially of the old coalfield where exist lots of old gobs. This paper would took an example as a mine in the Jincheng coalfield . using Transient Electromagnetic Method and Audio Electrical Prospecting Method to detecting the aquiferous gob which around the mine, which based on the point that the aquifer layers are easily be detected by TEM and the Audio Electrical Prospecting Method can reduce the TEM’s volumetric effect. comprehensive analyze the characters of the two detect method about aquiferous gob, the area of the aquiferous gob can be got accurately, which provide the basis for the work about water drainage in mine.
