采矿设计是矿山建设和运营的一个关键环节。采矿设计需要综合考虑矿山资源状况、开采技术条件、矿产品销售价格、矿石开采及处理成本等多种因素，以实现经济效益最大化。目前三维矿床模型和采矿三维设计方法的完美结合使采矿设计更为简化，并可获得良好的动态效果。以利比里亚某铁矿为例，利用3Dmine三维矿业软件，建立了地表地形、矿体实体和块体模型。在此基础上进行了露天开采境界优化、开拓运输系统布置、采剥进度计划编制等采矿设计。结果直观反映了采矿设计方案及数据变化关系。同时讨论了不同矿石价格及不同台阶对露天境界的影响，分析了不同条件下剥采比的变化情况。在实际生产中，可根据不同情况适时调整露天开采境界，以实现最优的矿山经济效益。

Mining design is a key link of mine construction and operation. In order to maximize economic benefits,re-source condition,mining technical condition,mineral products price,ore mining and processing costs etc. should be considered in mining design. At present,the combination of 3D deposit model and mining design makes the mining design more simplified, and good dynamic effect is obtained. Taken a Liberian iron mine as an example,terrain model,solid model and block model of ore bodies are built by using 3DMine software. On this basis,mining designs including the open pit boundary optimization,de-velopment and haulage system and the stripping schedule are made,which directly reflect the mining plan and the data chan-ges. Effect of different prices and steps on boundary optimization is discussed to analyze the variation under different stripping rate. In practical production,open-pit boundary can be adjusted according to the different situation to realize the best economic benefits.
