CUGTEM-8 Mine Transient Electromagnetic Instrument

The mine transient electromagnetic method is the same as the ground transient electromagnetic method. The difference is that mine transient electromagnetic method is carried out in the underground roadway with widely spatial distribution and the entire space effects become the inherent problem of mine transient electromagnetic method. Since the seam under normal circumstances is the high resistance media and the electromagnetic waves can go through easily, so the seam doesn't exsist DC electric field shielding for the TEM and the signal the receiving coils received is from the comprehensive reflection of the entire space electric rock arounding the launching coils. Thus in the determination of abnormal body position in space, we should rely on the normal direction of planar coils in combination with a comprehensive analysis of geological data for identification.
with the detecting depth from 50M to1300M CUGTEM-8 can be used for underground polymetallic deposit and water search, salt and fresh water distinction, underground electricproperty stratification, underground water-filled cave delineation and steep angle geological structure detection, Particularly applicable to the coal seam, coal mined-out areas (collapse areas), and water-filled area detection. Besides, it also can accomplish applications in some other aspects such as the geothermal resources search, the oil and gas fields investigation and exploration in the high-resistivity covered areas( such as the carbonatite, anorthosite, tundra covered area) and so on.
