生命周期评估（LCA）有助于量化采矿项目的环境成本，但LCA的应用往往是对运营矿山的追溯性环境测量。本文提出了一种新的方法进行生命周期评价，以产生生命周期影响评价数据，可以形成一个存款的环境块体模型。这些空间上明确的数据，然后可以用作长期矿山调度模拟内的约束。结果表明，可以以很小的经济代价显著减少全球变暖的影响。例如，使用环境约束，与基线相比，可以实现91.9%的全球变暖影响，同时实现95.9%的净现值。不同的约束条件和经济情景进行了探讨，并进行多标准决策分析。这一办法使环境因素能够纳入战略性采矿规划。这一点很重要，因为在可预见的未来，采矿将继续成为我们社会的重要组成部分。将环境因素纳入采矿规划的最早阶段，有助于推动对环境负责的原材料开采。
Life cycle assessments (LCA) are useful to quantify the environmental costs of mining projects, however the application of LCA is often a retrospective environmental measurement of operating mines. This paper presents a novel methodology of carrying out a LCA to generate life cycle impact assessment data that can form an environmental block model of a deposit. These spatially explicit data can then be used as a constraint within long-term mine scheduling simulations. The results indicate that significant reductions in global warming impact can be achieved at a small economic cost. For example using an environmental constraint it was possible to achieve 91.9% of the global warming impact whilst achieving 95.9% of the net present value compared to the baseline. Different constraints and economic scenarios are explored and multi-criteria decision analysis is carried out. This approach enables environmental considerations to be included in strategic mine planning. This is important because mining will continue to form an important part of our society for the foreseeable future. Integrating environmental considerations into the earliest stages of mine planning can assist in driving environmentally responsible raw material extraction.
