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。 A mixed integer model of macroeconomic optimization for opencast mining with comprehensive consideration of mining sequence, site selection, transportation routes, ore blending and other decision-making factors was established, and the time effect of capital was considered to minimize the investment cost. Through the example, the advanced optimization software is used to verify the model, which provides theoretical and practical guidance for the decision-making of mining design optimization.
