High-power in-well induced polarization technology and its application in theXiaoqinling gold deposit

Geophysical exploration methods in Wells are widely applied as an important and effective exploration approach in deep mineral exploration. This time, a 150 kW high-power electromagnetic detection system was applied to conduct research on in-well excitation polarization technology for metal mineral boreholes over 2,000 meters in the ZK1 borehole of the Xunma Road Fault in the Xiaoqinling Mountains. By means of ground-well observation and four-directional measurement, in-well excitation electric measurement was carried out on the 815 m to 2260 m section of the ZK1 borehole to determine whether there are blind mines at the bottom and beside the well. At the same time, determine the direction of the ore body to provide a direction for the next deep mineral exploration work.
