新分类标准下多金属矿床露天边界品位的确定方法

Rational Determination of Open-pit Cut-off Grade for Multiple Metal Deposits under the New《Resources/Reserves Classification Standard》

为推广应用新的储量分类标准,以国外矿业软件平台为工具,按开采利润净值最大原则对多金属复杂矿床边界品位的确定方法进行了深入研究,提出了一套与新储量分类分级标准配套,经实践证明切实可行的多金属矿床露天边界品位确定方法和步骤,为地勘单位、生产矿山确定边界品位提供了依据。

For extensive application of the new《Resources/reserves classification standard》, a deep - going study was made on the method for rationally determining the cut - off grade of complex multiple metal deposit in the principle of maximum net mining profit by means of a foreign mining software platform. A set of methods and procedures for rational determination of cut - off grade of multiple metal deposits in the complementation of the new classification standard for reserves were proposed, which have been proven to be feasible in practice, thus providing a basis for determining the cut - off grade for geological exploration units and production mines.
