Application research of GDD induced polarization instrument
The coal industry has long faced the problem of preventing and controlling mining water disasters.Compared with high-density direct current method,GDD high-power direct current induced polarization instrument has the advantage of larger exploration depth.Compared with the V8 transient electromagnetic instrument,it has strong anti-interference ability and can still collect reliable signals in electromagnetic interference areas.The article confirms the effectiveness of the GDD high-power induced polarization instrument in coal mine hydrogeological exploration,selects suitable device forms and working parameters,provides preliminary experimental research for production practice,and provides a research foundation for the production application of the instrument.
