摘要
为了克服在低品位矿石利用的研究中现行方法只以企业效益为目的的局限性，试图建立起一套以国民经济整体效益优化为目标的系统的分析方法，研究中运用了费用效益分析技术并辅之以半投入产出法、增量分析法和动态经济分析法。在以露天开采作业为对象的基础上，提出了三个临界品位计算的数学模型（这些模型很容易扩展到地下开采的情形之中），最后给出了一个计算实例。
In order to overcome the limits of current approaches which aim at the maximization of corporate profits in the analysis of utilizing low grade ores, a systematic analytical methodology for economic efficiency analysis was established, which aimed at the optimum allocation of national resources, utilizing cost benefit analysis and assisted by semi imput output analysis, incremental analysis and dynamic economic analysis. Three mathematical models for critical grade calculations were presented based on openpit operations and they may be easily extended to underground mining. Finally, a working example was given.
