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.
