摘　　要：本文以净现值最大为优化目标,考虑采、选两阶段因素,给出了矿产储量统计和地下开采矿体边界品位动态优化的数学模型。在此基础上,结合矿山的品位分布和采矿方法,提出整体优化和部分优化的思路,并通过计算机软件系统实现。其结果可以用来指导矿山长期、中期和短期的规划和生产。Use maximum net present value as an optimum target with consideration of t 他 two- phase factors mining and milling, a dynamic optimum method for optimizing cutoff grade of underground mine deposit is given. Base on this, Offer the idea of total and part of the mine optimization consider of the grade distribution and mining methods, then implement it by computer software system. The result can instruct mine＇s long , mid and short term plan and production.

关 键 词：地下开采 边界品位 优化
