本文旨在概述一种用计算机计算的净现金流量来确定实际边界品位的方法。边界品位不仅具有地质意义,而且具有经济意义,后者,将费用与收益进行权衡。对于不同情况来说,边界品位都是一种“评价标准”,这种标准是为在特定时期划分经济的或不经济的矿物储量确定的。在经常变化的技术经济环境中,按矿山最佳经济潜力来发展或维持其经营的决策,要求采取适当的边界品位策略,即与企业短期及长期经营目标相一致的策略,也是根据实际销售条件和金属价格预测而制定的策略。评价矿山的计算机程序与企业的具体净现金流量要求的联合应用,是优化边界品位最有前途和最灵活的配套方法。
This article aims to outline a method of using computerized net cash flow to determine the actual boundary grade. The quality of the boundary not only has geological significance, but also has economic significance. The latter balances the costs with the proceeds. For different situations, the boundary grade is an “evaluation criterion” that is established for the purpose of dividing economic or uneconomic mineral reserves over a specific period of time. In a constantly changing technological and economic environment, the decision to develop or sustain its operations in terms of the optimal economic potential of the mines requires the adoption of an appropriate border-level strategy that is consistent with the short-term and long-term business objectives of the enterprise and also based on actual sales conditions And metal price forecasting strategy. Evaluation of the mine’s computer program and the specific net cash flow requirements of the joint application is to optimize the most promising grade of the border and the most flexible matching methods.
