矿山建设前期工作,可分为矿山建设的初始阶段和投资决策阶段,前者为矿床的普查勘探经济效果评价工作,后者为建设前的项目可行性研究工作。诚如所知,勘探中获得的矿石储量和地质信息,仅具有潜在价值,只有获得商品矿石产品后才具有使用价值,才能评价其经济效果。因此,这个阶段 The preliminary work of mine construction can be divided into the initial stage of mine construction and the stage of investment decision-making. The former is the evaluation of the economic effect of the census and exploration of the deposit and the latter is the feasibility study of the project before the construction. As we all know, the ore reserves and geological information obtained during the exploration have only potential value. Only after obtaining the commercial ore products will they have the use value, so as to evaluate their economic effects. Therefore, this stage
