In Tongling copper mine of Anhui Province, the authors conducted a series of transient electromagnetic exploration immunity tests using GDP-32Ⅱ. Different parameter settings were compared with each other by changing wire size, current, frequency, number of times of superimposition on the frequency and observations, so as to provide an effective measure for obtaining real and reliable data in the strong interference area.
