摘要

摘要矿床估算模型中应考虑稀释效应，因为稀释效应对可行性研究、矿山规划和调度、选矿和堆存具有重大影响。这项工作比较了两种方法对铜矿床矿体中侵入性贫瘠岩脉稀释的建模能力。使用两种方法生成铜矿床中铜品位的未稀释模型，该模型被侵入岩脉横切。结果表明，与第一种方法相比，第二种方法更有利，尤其是当矿石和贫瘠的岩脉之间存在硬接触时。

Comparing the accuracy of two approaches to account for internal dilution: A case study from a porphyry copper deposit

ABSTRACT Dilution effects should be considered in the estimated model of deposit due to its significant impact on feasibility studies, mine planning and scheduling, milling, and stockpiling. This work compares the capacity of two approaches for modelling dilution of intrusive barren dykes into the ore body in a copper deposit. Two approaches were used to generate an undiluted model of copper grade in a copper deposit, which is cross cut by intrusive dykes. The results demonstrated that the second approach is more advantageous in comparison with the first approach, especially when there is hard contact between the ore and barren dykes.
