In oil sands open-pit mining, further processing of the extracted oil sands generates massive volumes of tailings. To save space, the tailings are deposited in in-pit tailings containments constructed by internal dykes using mine waste material. In this paper, an integrated mine planning framework is proposed and implemented using mixed-integer linear programming to optimize the production schedule with respect to dyke construction and in-pit tailings deposition. A case study is carried out to verify the performance of the proposed optimization model. The results demonstrate how the produced tailings are deposited in the excavated mining pits as the mining operation proceeds and the in-pit dykes are constructed using mine waste material. The framework facilitates sustainable oil sands mining through a reduced environmental footprint.

用于油砂生产计划和尾矿管理的混合整数线性规划

在油砂露天开采中，对提取的油砂进行进一步加工会产生大量尾矿。为了节省空间，尾矿被存放在由内部堤坝使用矿山废料建造的坑内尾矿安全壳中。在本文中，提出并实施了一个综合矿山规划框架，使用混合整数线性规划来优化有关堤坝建设和坑内尾矿沉积的生产计划。进行案例研究以验证所提出的优化模型的性能。结果表明，随着采矿作业的进行，产生的尾矿如何沉积在挖掘的矿坑中，以及如何使用矿山废料建造坑内堤坝。该框架通过减少环境足迹促进可持续油砂开采。
