摘      要：Pit limit design has,up to date,focused mainly on maximization of economic profit alone,with environmental and social issues largely *** 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 *** 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 *** the ecological costs are factored in,the optimal pit limit is 37.5%smaller than the economically optimal pit ***,when the social benefits are factored in,the optimal pit limit is 48.3%larger than the economically optimal *** 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.
