摘　　要：本文以四川省某铁矿作为实例,在建立地表模型、地质数据库、矿体模型、块体模型的基础上,采用3Dmine矿业软件,在不同条件下,进行露天境界优化,并得出了不同矿石价格、不同品位变化、不同边坡角下的露天境界,同时,分析了不同条件下剥采比变化规律;对比三种条件下优化结果的不同,在综合考虑市场矿石销售价格波动和开采成本变化下,实现经济效益最大化。This paper taking a iron ore mine in sichuan province as an example, in establishing the surface model, geological database, ore body model, the block model, on the basis of using mining software, 3 dmine under different conditions, the open boundary optimization, and it is concluded that the different ore price and grade change, open state under different slope angles, at the same time, the stripping ratio variation law under different conditions are analyzed. By comparing the different optimization results under the three conditions, the price fluctuation of ore sales and the change of mining cost are taken into account, maximize economic benefits.
