过去,我国由于未重视矿床勘探和开发的经济效益,很少进行矿床工业指标(品位指标是最主要的指标之一)的深入研究.有些矿床的工业指标是50年代制订的.当初制订时,就缺乏深入的技术经济论证,而一旦制订之后,又往往长期不变,不同开采条件的矿床(如露天矿和地下矿),不同工业类型的矿石(如磁铁矿石和赤铁矿石)都采用同样的指标.这显然是很不恰当的. 北京科技大学以陈希廉教授为首的地质经济科研组,近十年来进行了9个铁矿床、1个铜矿床边
In the past, our country did not pay much attention to the economic benefits of exploration and development of mineral deposits, and we did not do any further research on the industrial indicators of ore deposits (the grade index is one of the most important indicators) .Industrial indicators of some deposits were formulated in the 1950s, There is a lack of in-depth techno-economic justification. Once developed, deposits of different industrial types, such as magnetite ore and hematite ore, are often used in deposits of different mining conditions (such as open-pit mines and underground mines) The same indicators .This is obviously not appropriate.Beijing University of Science and Technology Professor Chen Xilian geology and economics research group led by nine years, carried out in the past decade nine iron deposits, a copper deposit edge
