Detailed Product Description

Portable Shallow High-Resolution Transient Electromagnetic

TEM design

 

•Use a single TEM coil for multiplexing to eliminate the mutual inductance of the transceiver coils
• Multi-level current transmission, low current (short off time) transmission to ensure shallow resolution detection, high current transmission to ensure exploration depth
• Dual-channel synchronous detection, strong signal channel to ensure high-fidelity and large dynamic range detection of early TEM signals, weak signal channel to ensure high-fidelity detection of late TEM signals
• Use complex hardware and algorithms to replace complex TEM antennas, and use a single coil to realize TEM signal transmission and reception
• The exploration resolution and exploration depth are equivalent to those of a 40×40m coil, the shallow exploration resolution reaches the meter level, and the maximum exploration depth exceeds 100-200 meters

Application

 

Transient electromagnetic method is a new generation of electromagnetic exploration method that is rapidly developing and popularizing because it has many advantages that traditional direct current method cannot match. According to the working airspace, transient electromagnetic method can be divided into aviation transient, ground transient, underground (mining) transient, and marine transient. This article mainly deals with underground transient (mine transient electromagnetic method).

  • Groundwater detection. Transient electromagnetic method can be used to find water, distinguish between fresh and salt water, stratify underground electrical properties, and delineate underground water-filled caves;
  • Find polymetallic deposits;
  • Detection of coal seams and coal seam goaf (collapse) areas and their water-filled areas;
  • Detection of steep dips, faults, veins and other geological structures.
