Surface electromagnetic prospecting system (SEP) comparative test on Jinchuan nickel mine of Gansu Province

Surface electromagnetic prospecting system (SEP) has got good results in comparison test with commercial high-end instruments in Yangjiazhangzi mine Xingcheng, Liaoning province. The comparison test of SEP system and commercial instruments was continue carried out in Jinchuan Nickel Mine Gansu province, where the noise is very strong, in order to test the SEP performance and reliability of each component, as well as the overall system performance in practical work, in the strong interference area. It shows that the SEP system has considerable anti-interference ability compared with international advanced equipment, and is highly suitable in a varity of complex tasks, that is the good consistency of different transmitters, different receivers original curve, and inversion profile for both systems.
