新分类标准下多金属矿床露天边界品位的确定及应用

Determination and Application of Open-Pit Cut-Off Grades of Multi-Metal Deposits under New Classification Standards

为适应新的固体矿产资源/储量分类标准的推广应用,针对传统手工双指标法圈定矿体存在的问题,采用国外矿业软件平台作为工具,以开采利润净价值最大原则对多金属复杂矿床边界品位的确定方法进行深入研究,提出一套与新储量分类分级标准配套,经实践证明切实可行的方法和步骤,为地勘单位、新建矿山和生产矿山确定边界品位提供了依据。

To adapt to spreading the application of new classification standards for solid mineral resources/reserves and in the light of the problems existing in traditional double-indicator manual deposit delineation method, a deep-going study was made on the method for determining the cut-off grade of multi-metal complex deposits in the principle of maximum net mining profit by means of a foreign mining software platform. A set of methods and procedures in the complementation of the new classification standards 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, new mines and production mines.
