摘　　要：通过灰色系统理论对矿区内各矿脉进行了关联分析,表明区内高产矿脉28号脉与43号脉关联度较高,结合含矿构造的特点及物化探数据异常,判定43号脉有成矿远景。在灰色建模中,以矿脉长度代表矿化的白化值,经过数据处理建立灰色预测模型GM(1,1),通过残差检验确定了模型的可靠性。By using the grey systematic theory, the association analysis on the ore veins in the mining area is made, showing that high - yield Vein 28 is closely related with Vine 43. On the basis of the characteristics of the pay structure and the anomalies of geophysical prospecting and geochemical exploration data, it has been decided that Vein 43 should belong to the mineralizing prospect. In the grey systematic model, the linear scale indicates the degree of mineralization. Through residual error verity, the reliability of model is definited.
