边际效益法在露天采矿分期境界优选中的应用

Application of Margin Benefit in Determining Rational Open Pit Mining Limit of Mines

本文阐述了边际理论的基本原理,提出了边际效益的概念。针对用参数化函数法搜索所得的多个露天采矿分期境界方案,运用边际效益法进行了比较决策,得出了分期开采的最优境界方案,为确定矿山的合理开采境界提供了一种新的技术手段。

The basic principle of margin theory is stated, and the concept of margin benefit is brought forwarded in this paper. Aiming at multi-ptojects of open pit mining limits obtained by parameter-function method, using margin benefit to determine the rational mining limit, it succeed in obtaining the best design of open pit limit, which is obtained from the counting result of parameter-function method. A new method is provided to determine the rational open pit mining limit in this paper.
