灰色聚类决策在露天采矿分期境界优选中的应用

本文阐述了灰色决策理论和灰色聚类决策的基本原理。针对露天采矿分期境界设计中用参数化函数法搜索所得的多个分期境界方案,提出了一种基于灰色定权聚类和白化权函数的灰色聚类决策方法,实现了露天采矿分期境界设计的灰色聚类决策,得出了分期开采的最优境界方案和可行境界方案。应用证明,该方法在露天采矿分期境界优选设计中是切实可行的,为确定矿山的合理开采境界提供了一种新的技术手段。

Application of Grey Clustering Decision in Determing the Rational Staged Pit Limit of an Open-pit Mine

The basic theory of grey decision-making and grey clustering decision is stated in this paper. A kind of grey cluster assessment method for determining the rational staged pit limit of an open-pit mine is proposed based on grey fixed weight clustering and white-ionization weight function. The grey clustering decision has been successfully used in design of the rational staged limit of an open-pit mine, thus obtaining the optimal and feasible limits from many limit options which are obtained from the counting result of parameter-function method. The Application shows the assessment method is practical for determining the rational staged pit limit of an open-pit mine. This method can be used as a new means for determining the rational mining pit limit of an open-pit mine.
