Aimed at tackling the problems of low efficiency and the need of high data quality of IP observation methods in borehole, the authors developed a new device of borehole IP prospecting in this paper. The device can be used to measure the polarization field potential (V), potential difference (ΔV), secondary field potential (V2), potential difference (ΔV2) and time information (T) simultaneously by full waveform electrical method, and then obtain various IP parameters. In order to test the validity of the method, the authors studied the application of full waveform array IP to a copper-gold deposit in Anhui Province, obtained the connectivity of the drilled orebody, and determined the direction and distribution range of the orebody. The application results show that this bolehole IP observation of full waveform array method has high efficiency and strong anti-interference capability.
