摘　　要：某地经由前期地质人员通过大量实地查勘与槽探工作,大致查明了区内基本地质特征、金矿点分布和矿体的规模、产状、形态,初步查明了矿石的结构构造、物质成份等。但要开展生产活动,仍需进一步对矿区内不同岩性及矿层的物性差异进行测试分析;寻找和圈定硫化物富集体及成矿有利带,推断其金矿(化)体分布范围、规模及赋存状态。利用激发极化法对矿区进行中梯扫面及测深工作,更好地为地表工程揭露和深部工程验证提供了依据。Through a lot of preliminary field survey and trenching work, the basic geologic feature, gold spot distribution and the scale, occurrence and shape of the mine are generally found out. The structure and component of the ore are initially found out. But it is necessary to analyze the different lithology and physical property of seam in the mine, to find and identify areas collective and rich sulfide mineralization favorable zone and guess the gold ore distribution scope, scale and occurrence. Induced polarization method is used to do ladder scanning and sounding work, providing basis for surface engineering revealing and deep engineering verification.
