【摘要】 建立了综合考虑开采顺序、选址、运输线路、配矿等决策因素的铝土矿露天开采宏观运营优化的混合整数模型,并考虑了资金的时间效应,以实现投资成本最小化。通过实例,运用先进的优化软件求证了这一模型,为企业开采设计优化决策提供了理论和实践指导。更多还原

【Abstract】 A mix integer model for the optimization of macroscopic operation of open-pit mining of bauxite deposit was established,in which such decision-making factors as mining sequence,location of open-pit working,transportation line and ore blending are took into account,and the time effect of capital to realize the minimum cost of investment has been considered also.The model was proved using an optimization software and by an example mine.It can provide guidance in theory and practice for the decision-making optimization of mining design of bauxite deposit.更多还原
