The Mine Borehole Transient Electromagnetic Detection System is a high-precision detection system developed based on multiple proprietary patented technologies to meet the precise detection requirements outlined in the *Specifications for the Survey of Hidden Hazardous Factors* and the *Detailed Rules for Coal Mine Geological Work*. It is primarily used for the precise detection of abnormal water-bearing bodies around boreholes in coal mines, as well as for monitoring the effectiveness of grouting and fracturing operations. This equipment offers four key advantages. First, it enables efficient multi-purpose exploration within a single borehole by integrating transient electromagnetic detection and borehole inclination measurement functions. Second, the system employs directional shielding technology to effectively suppress interference signals from non-detection directions, thereby achieving three-dimensional imaging of anomalies surrounding the borehole. Third, it delivers high signal acquisition accuracy through the use of optical isolation, blanking circuits, 24-bit high-speed ADCs, and signal superposition technology, resulting in low background noise. Fourth, it offers broad applicability, suitable for use in coal resource and mining geophysics, as well as tunnel and underground engineering geophysics.
