摘　　要：以岩 (矿 )石的导电性和激电效应差异为基础 ,沿测线同时布设几十到几百根电极 ,仪器按选定的供电、测量排列方式自动采集电位值 ,并进行滤波、地改、计算等处理 ,可探测深度在15 0m以上的电阻率和充电率的精细结构 ,用以推断精细的地质和电子型导电矿物结构。在不同地区、不同类型的已知金矿床的试验表明 ,高密度电法异常与矿体在空间位置上十分吻合 ,在未知区 ,在异常区施工QZ14 2钻孔 ,发现了地下 38m的盲矿体 ,取得了满意的试验和找矿效果。Based on the electrical conductivity and excitated electrical conductivity character of the rocks and mineral, set out tens to hundreds of electrodes along the measuring-line. The instrument automatic receives the potential value of every electrode by selected power supply mode and survey array mode. By filter, topographically and calculate with the value, the micro-character of resistivity and induced polarization that less than 150 meters underground can be explored, then deduce the micro-character of geological and electron conducting mineral. This method had been used in different area and different types of gold deposits. The high-density resistivity anomaly is suit well with the practical deposit body in site. In some unknown area, unknown deposit bodies were found underground 38 meters by QZ14-2 drill hole. This method has made satisfied experiment and exploration result.
