摘要
贫富兼采系统工程是一项广泛的经济行为。为此需要在统一的计划下,首先求导高于特定矿产品市场价格的宏观调控型影子价格及其控制的品位指标系列,以便在合理满足社会长远需求和保证各个矿山收支平衡有余的前提下,最大限度地放宽贫矿的下界。整个系统工程需要从最初等丰度矿山的最初等丰度块段入手,之后扩展到整个矿山,一个集团公司的各个矿山、一个地区的各个矿山乃至全国的同类矿山。
The system engineering of exploitation of low-grade ore and high-grade ore simultaneously is a wide economic behavior.For this purpose,shadow price of macro-control type which is higher than the market price of a particular mineral products and controlled grade indicators should be derived under the unified scheme,so that on the premise of reasonably meeting the long-term needs of society and ensuring the balance between income and expenditure of all the mines,we can relax the lower bound of lean ore to the utmost.The whole system engineering extends gradually from one mine to the whole.
