开采境界设计主要是考虑经济利润的最大化,忽略了环境和社会问题的影响.本文重点考虑将环境和社会问题纳入最终开采境界设计过程,并提供一种符合可持续发展的最终开采境界优化方法.研究表明,生态成本对最终开采境界具有显著的缩减效应,而社会效益具有显著的扩增效应.考虑生态成本后,最终开采境界比经济最优境界小37.5％.然而,当考虑到社会效益时,最终开采境界比经济最优境界大48.3％.综合考虑经济利润、生态成本和社会效益得到的总体最优开采境界是通过平衡经济利润最大化、生态成本最小化和社会效益最大化相互冲突的结果.
Open pit limit optimization considering economic profit, ecological costs and social benefits
Pit limit design has, up to date, focused mainly on maximization of economic profit alone, with environmental and social issues largely ignored. This paper focuses on incorporating both environmental and social issues in the pit limit design process and provides an approach to pit limit optimization that is in compliance with sustainable development. The case study demonstrates that ecological costs have a substantial down-sizing effect and social benefits have a substantial up-sizing effect on the optimal pit limit. When the ecological costs are factored in, the optimal pit limit is 37.5％ smaller than the economically optimal pit limit. However, when the social benefits are factored in, the optimal pit limit is 48.3％ larger than the economically optimal one. The overall optimal pit limit, with the economic profit, ecological costs and social benefits simultaneously considered, is a result of balancing conflicting goals of maximizing economic profit, minimizing ecological cost, and maximizing social benefit.
