地面电磁探测(SEP)系统对比试验——内蒙曹四夭钼矿

Surface Electromagnetic Prospecting System(SEP)contrast test in Caosiyao molybdenum mine,inner mongolia

为了检验自主研制的地面电磁探测(SEP)系统各组成部分在实际勘查中的性能与可靠性,以及整体系统的野外实际工作能力,在内蒙古乌兰察布市兴和县的曹四夭钼矿开展了SEP不同类型磁传感器之间以及SEP整套系统与国外商业仪器系统的全面对比试验.试验采用多种方案,分别进行了高温超导磁传感器和感应式磁传感器之间的性能对比试验;磁通门磁传感器和感应式磁传感器之间的性能对比试验;SEP发射机与GGT-30发射机、TXU-30发射机的发射性能对比试验;SEP系统与V8、GDP-32II等国际先进仪器的CSAMT法综合对比试验;以及SEP系统和V8系统的MT法对比试验.本文对试验结果进行了分析,表明自主研制的SEP系统已经基本达到甚至优于国外同类产品的性能,能够很好地胜任野外实际勘查工作.

In order to test the performance and reliability of each component of surface electromagnetic prospecting（SEP）system in practical exploration,and the overall ability of SEP system in field work,a test is conducted at Caosiyao molybdenum mine in Xinghe,Inner Mongolia,which is a comprehensive test involving each component of SEP system.Using a number of schemes,several contrast tests had been carried out,including contrast test between high-temperature superconducting magnetic sensors and coil magnetic sensors,contrast test between fluxgate magnetic sensors and coil magnetic sensors,transmitting performance contrast test among SEP,GGT-30 and TXU-30 transmitters,CSAMT contrast test among SEP,V8 and GDP-32 II systems,and MT contrast test between SEP and V8 systems.This paper analyzes the test results which show that self-developed SEP system has basically reached or exceeded the level of the similar foreign products,and is competent for the practical exploration work in the field.
