Technology and application of in-advance geophysical detection in coal mines

The paper introduces underground geophysical detection technology applied in coal mines, focusing on the improvement of in-advance geophysical detection techniques such as Rayleigh wave and direct current methods. In combination with the application in Qitaihe, Pingdingshan and other mines, the potential of in-advance geological prediction in underground mines was analyzed and the development orientation of in-advance underground geophysical detection technology was put forward.
