First, shallow transient electromagnetic exploration has high construction efficiency, pure secondary field observation, and sensitivity to low-resistance bodies, which makes it the preferred method in coalfield hydrogeological exploration. This method is most sensitive when looking for low-resistance geological bodies in high-resistance surrounding rocks and is not affected by terrain.
Second, shallow transient electromagnetic exploration uses combined observations at the same point, has the best coupling with the detection target, strong abnormal response, simple morphology, and strong resolution. Profile measurement and depth measurement are completed at the same time, providing more useful information.
In addition, shallow transient electromagnetic exploration shows high value in application cases in specific areas. For example, by measuring and analyzing the secondary magnetic field underground, it can be found that the electrical characteristics of the rock formation are significantly different from those in the surrounding area, and it is speculated that there may be mineral resources. After further geological exploration and drilling verification, it was confirmed that there are indeed metal ore bodies of a certain scale in the rock formations in the area.
Finally, shallow transient electromagnetic exploration is usually combined with other exploration methods in practical applications to improve the accuracy and reliability of mineral exploration. This method also has high application value in finding hidden minerals, and can overcome the difficulties of conventional exploration methods.
