Geophysical exploration methods mainly included electrical, magnetic, gravity, seismic and radioactive methods. The most widely used geophysical exploration in coal mine is electrical method. This paper mainly introduced the first-hand data collected by four commonly used underground geophysical exploration methods in Jiulong Mine, including transient electromagnetic, radio wave tunnel perspective, electrical sounding and amplitude-frequency electrical perspective. Combined with the results of later drilling verification of geophysical anomaly areas by the mine, this paper studied whether the parameters of different geophysical exploration methods could define an absolute value, which could determine whether there was a real anomaly area.
