一、矿床经济价值矿床经济评价是用货币形式反映其经济价值。探明矿量经济价值只有通过矿山实体物质生产过程才得以实现。按矿山开发不同阶段经济评价划分,矿山生产阶段经济评价是矿床经济评价最高层次。这个阶段,评价的经营参数业已经过生产实践,能使评价结果建立在较可靠与准确基础上。评价结果对相同类型矿床的勘探阶段经济评价,对地区资源形势分析,对矿产资源管理,也可提供参考。梅山矿1970年采矿投产,1980年建成一期采选联合系统。1987年达到设计年产150万吨原矿,成为目前国内最大的坑下铁矿。为了满足对钢铁的需求,国家决定在“七·五”期 First, the economic value of the deposit Economic evaluation of the deposit is reflected in monetary terms its economic value. The economic value of proven mineral resources can only be realized through the process of physical material production of mines. According to the economic evaluation of different stages of mine development, the economic evaluation of mine production stage is the highest level of economic evaluation of the deposit. At this stage, the evaluation of business parameters have been produced in practice, can make the evaluation results based on a more reliable and accurate basis. Evaluation results of the same type of exploration of the economic evaluation of the stage, the regional resource situation analysis, the management of mineral resources may also provide a reference. Meishan Mining put into operation in 1970, built in 1980, a joint mining system. In 1987, it has reached a designed annual output of 1.5 million tons of ore, making it the largest underground iron mine in the country. In order to meet the demand for steel, the state decided to “seven five” period
