摘　　要：为延长珲春紫金曙光金铜矿露天采场的服务年限、充分利用资源,基于地质品位模型、当前技术经济参数和地表约束界线,采用Whittle软件进行多方案的境界优化。与原设计境界相比,多采矿、少剥岩、降低生产剥采比,并延长服务年限。同时,分析了价格变化及边坡角进一步加陡对境界产生的影响。In order to extend the service life of the open-pit mine in the Hunchun Zijinshuguang gold and copper mine, and make the best use of the resources, Whittle software was used to optimize the mining boundary under different scheme based on the grade model and current technological and economical parameters and surface boundary line. Comparing with the original boundary, it can exploit more ore rock and less rock and reduce the production stripping ratio and extend the service life. At the same time, the article analyzes the impact of price changing and slope angle steeping on boundary.
