摘　　要：为探明百地金矿区4号矿体深度方向上电性异常分布特征,为矿方进一步施工提供依据,在参考结合矿区地质和岩、矿石电性特征的基础上,介绍了频谱激电测深方法的原理及装置方式和跑极方式,对已知地质情况和异常分布的3号矿体311剖面进行试验工作,取得良好效果后,以相同参数应用于未知地质情况的4号矿体400剖面,获得了4个视频谱参数反演图,圈定了异常体范围,并进行钻探验证工作。结果表明:频谱激电测深法应用于金矿探测效果好、精度高,对异常体反映准确。In order to find out the distribution characteristics of electrical anomaly in the depth direction of No.4 orebody in Baidi gold mine area,and provide the basis for further construction of the mine,based on the geological and electrical characteristics of rock and ore in the mining area,this paper introduces the principle of frequency spectrum induced polarization sounding method and its device mode and pole running mode.The 311 section of No.3 orebody with known geological conditions and abnormal distribution is tested.After good results are achieved,the same parameters are applied to 400 section of No.4 orebody with unknown geological conditions,and four video spectrum parameters are obtained,the abnormal body range is delineated and verified by drilling.The results show that the spectrum induced polarization sounding method has good effect and high accuracy in gold exploration,and can accurately reflect the abnormal body.
