摘　　要：煤炭行业长期面临着开采水灾害防治问题。GDD大功率直流激电仪与高密度直流电法仪相比具有勘探深度大的优点;与V8瞬变电磁仪相比抗电磁干扰能力强,在电磁干扰区域仍然能够采集到可靠的信号。文章确定了GDD大功率激电仪在煤矿水文地质勘查中的有效性,选择适用的装置形式和工作参数,为生产实践提供前期试验研究,为该仪器的生产应用提供研究基础。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.
