大型露天金属矿地球化学成矿预测模式构建
|
摘要
为了对大型露天矿山的有色金属矿进行定量预测评价,建立基于地球化学的金属矿成矿预测模式。以某大型露天有色金属矿区为参照,提取矿区的有利成矿信息,包括矿区地层、岩体、构造等特征,在此基础上,结合地球化学的定量理论,构建金属矿成矿综合预测模型。成矿预测对比结果表明,地球化学成矿预测模式适用于对隐伏矿体的预测,能够服务于大型露天矿区的找矿勘探工作。
In order to quantitatively predict and evaluate the non-ferrous metal deposits in large open pits, a metallogenic prediction model based on geochemistry is established. Taking a large open-pit nonferrous metal mining area as a reference,the favorable metallogenic information of the mining area is extracted, including the strata, rock mass, structure and other characteristics of the mining area. On this basis, combined with the quantitative theory of geochemistry, a comprehensive metallogenic prediction model is constructed. The comparative results of metallogenic prediction show that the geochemical metallogenic prediction model is suitable for the prediction of concealed ore bodies and can serve the prospecting and exploration work in large open pit mining areas.
