摘　　要：针对当前瞬变电磁勘探中存在的接收有效面积较小的问题,提出使用接收有效面积更大的磁棒代替传统的接收面积较小的空心线圈,并在山西大同进行了试验,取得理想的探测结果。将改进装置用于西藏某钼矿勘探中,探测深度达到1 000 m,远远超过原有装置的探测深度,为大回线源瞬变电磁应用于更深度空间探测矿和石油提供了可行性借鉴。This paper proposes the utilization of the magnetic probe that has larger receiving area to replace the air core coil which has too small receiving area.This design was realized in Datong,Shanxi Province.The authors used the improved arrangement in search for Mo deposits in Tibet,where the detection depth could reach 1 000 m,far larger than the detection depth of the traditional receiving system.The experiment and application of the improved receiving system make the application of TEM to oil and deep ore exploration feasible.
