摘　　要：在建立马关都龙曼家寨锡锌多金属矿床数学经济模型的基础上,依据不同边界品位多方案圈定矿体,并根据所计算出的净现值进行矿床经济评价研究,确定出矿床锌的最佳边界品位为3.2%,实现了矿山企业生产的动态管理和生产方案的优化决策与多目标规划;当锌的边界品位为0.97%时,在曼家寨锡锌多金属矿床开发的经济分析中,产品价格最为敏感,其次为产品成本,再次为投资总额,最为不敏感的是回收服务年限。The mathematical- economic model of Manjiazhai tin - zinc polymetallic deposit in Dulong town, Maguan city, was established. The ore deposit was delineated by the different cut - off grades, then, the net present value of the ore deposit was calculated, on that basis, the economic evaluation on the ore deposit was made,and the optimal zinc cut -off grade of 3.2% for the deposit was determined. The dynamic production management and the optimization decision and multiple - objective programming of production plan ere achieved in the mining enterprise. In the economic analysis of Manjiazhai tin - zinc polymetallie deposit development, when the cut - off grade of zinc is 0. 97% , the most sensitive factor is the price of the mineral products, the cost of the mineral products being the second, the total investment of mine being ten third, while the service life of mine is the least sensitive factor.
