摘　　要：地面电磁探测(SEP)系统在辽宁兴城杨家杖子矿与国外高端仪器对比试验中取得了不错效果.为了检验地面电磁探测(SEP)系统各组成部分在强干扰区中的性能及可靠性,以及由SEP系统各组成部分集成的整体系统的野外实际工作能力,继续在甘肃金川镍矿区,在强干扰背景下开展了与国外先进仪器的比对试验.利用SEP系统和国际高端著名商业仪器系统,通过不同发射机原始曲线、不同接收机原始曲线、反演剖面的对比,表明二者数据一致性较好,SEP系统的抗干扰能力已经和国际先进仪器相当,已经能够胜任各种复杂的勘探任务.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.
