摘　　要：境界优化是露天矿设计的重要环节,直接影响矿山的规模、投资、服务年限等各个方面。本研究以Surpac矿业软件系统为平台,以价值块体模型为核心,对某铜钼矿的开采境界进行优化。通过分析影响境界的主要因素,以钼价格和回收率为主要变量,进行了多方案比对研究。在比对的基础上,推荐最终境界,并完成了初步设计及矿(岩)量、剥采比、采出金属量等关键指标的计算。本研究为该矿资源开发利用提供了合理的技术方案和投资决策依据。同时,对类似的特大型低品位多金属矿床境界优化工作具有参考和借鉴意义。Open-pit optimization is an important part of open pit design, which directly affects the scale, the investment, service life and other aspects of the mine. Using the Surpae software as a platform and value block model as the core, the open-pit optimization of one Copper-molybdenum Mine is made. By analyzing the main factors affecting the pit,a multi-program comparison studies are conducted based on the price and recovery of Molybdenum which are the main variable. A final pit is finally recommended by comparison and the preliminary design is completed, and some key indicators are calculated such as mine（rock） quantity, stripping ratio and metal quantity. The study provides a reasonable technical solutions and investment decisions for the resource exploitation. Meanwhile, the open-pit optimization can be a reference by other similar large low-grade polymetal deposits.
