Wide area electromagnetic method is an electromagnetic exploration theory and method proposed by Academician He Jishan of Central South University. Based on this theory, Academician He Jishan's research group has invented the world's leading wide area electromagnetic instrument with completely independent intellectual property rights after years of scientific research. Compared with the traditional electromagnetic exploration method, the wide-area electromagnetic method has obvious advantages such as large detection depth, high detection accuracy, strong anti-interference ability and high work efficiency. "Large-depth high-precision wide-area electromagnetic exploration technology and equipment" won the first prize of the 2018 National Technology Invention.
In 2019, our company's Laguhe Gold Mine in Xiahe County took the lead in the province to use the wide-area electromagnetic method for geophysical prospecting. Practice has shown that the wide-area electromagnetic method has significant effects on stratigraphic division and structural identification, especially the identification and discovery of deep concealed structures, and has great practical guiding significance for the geological prospecting work of the mining area, indicating for deep prospecting Direction.
