%X We have implemented experiments on the known gobs in the Jiayuan Coal Corporation in Qinyuan of Shanxi using the method of dual frequency induced polarization.Through reorganising and analysising the data,we got that higher apparent resistivity rate and lower apparent ampli- tude-frequency rate exist in the gob without water by detection and the position of the gob underground was precisely given.The result turned out that the double frequency induced polarization method to detect the coal gob underground is feasible.
