米拉多铜矿露天开采境界优化研究

Study on the Optimization of Open-pit Mining Boundary in Milado Copper Mine

变化的技术经济参数对露天开采境界的确定存在影响。基于矿山更新的资源模型,综合考虑铜当量品位、台阶变化的采剥成本及复杂边坡角,通过设置多种不同参数的对比方案,应用专业的矿业软件对米拉多铜矿露天开采境界进行优化。研究确定了当前技术经济条件下矿山最优的露天开采境界,以及潜在的一系列露天开采境界。

The changing technical and economic parameters have an impact on the determination of open-pit mining boundary.Based on the updated resource model of the mine,considering the copper equiva-lent grade,the stripping cost of the step change and the complex slope angle,by setting a variety of different parameter comparison schemes,the professional mining software is used to optimize the open-pit mining boundary of Milado Copper Mine.The study determined the optimal open-pit mining boundary of the mine under the current technical and economic conditions and a series of potential open-pit mining boundaries.
