The oil sands are viewed as a vital component to the Canadian economy. At the same time, the environmental impacts of oil sands operations are also growing. Tailings impoundments are used almost exclusively for waste management, and the combined footprint for these impoundments is currently more than 220 km2. Processed oil sands ore yields a tailings slurry composed of water, sand, silt and clay (or "fines"), and a small amount of residual bitumen. The tailings are discharged into a settling basin, allowing the sand fraction to settle quickly on the beach with the balance of fine tailings settling in the pond. The Canadian Oil Sands Innovation Alliance (COSIA) and have partnered with UAlberta to significantly advance the rate at which tailings ponds can be reclaimed. The proposed research program consists of complementary themes that integrate multidisciplinary expertise from UAlberta and industry. The research proposes the development and application of new and innovative geotechniques to design dry stacked deposits for the oil sands industry while simultaneously investigating geotechnical and bio-geochemical aspects of current oil sands tailings management and reclamation strategies. The proposed research program focuses on: Theme 1: Engineered Mixtures of Tailings and Overburden for Dry Stacked Deposits Theme 2: Influence of Bio-geo-chemical Interactions on the Geotechnical Behaviour of Soft Tailings Theme 3: Capping Soft Tailings Deposits These complementary themes aim to conduct research that looks to the future of tailings deposits, while providing research for immediate/interim challenges. It is anticipated that 15 highly qualified personnel will be trained through the research program. Further, the collaboration between industry and academia will enable fundamental discoveries for the behaviour and improved management of fluid fine tailings, benefitting the engineering discipline, and bolster the University of Alberta and Canada's position as an international leader in mining reclamation and oil sands tailings geotechnique.

油砂被视为加拿大经济的重要组成部分。同时，环境 油砂作业的影响也在增长。尾矿库几乎完全用于废物处理 这些蓄水池的总占地面积目前超过220平方公里。处理 油砂矿产生由水、沙子、淤泥和粘土（或“细粉”）以及少量 残余沥青尾矿被排放到一个沉淀池，使砂部分迅速沉降 在海滩上，其余的细尾矿沉降在池塘中。 加拿大油砂创新联盟（COSIA）与UAlberta合作， 提高尾矿库的复垦率。拟议的研究计划包括 互补的主题，整合了UAlberta和行业的多学科专业知识。研究 建议开发和应用新的和创新的地质技术，以设计干燥的堆积矿床 同时调查油砂行业的岩土工程和生物地球化学方面， 目前的油砂尾矿管理和回收战略。拟议的研究计划侧重于： 专题1：干堆矿床的尾矿和覆盖层的工程混合物 主题2：生物-地质-化学相互作用对软尾矿岩土特性的影响 专题3：覆盖软尾矿矿床 这些互补主题旨在进行展望尾矿库未来的研究，同时 为即时/临时挑战提供研究。预计将有15名高素质人员 通过研究计划训练。此外，工业界和学术界之间的合作将使 流体细粒尾矿的行为和改进管理的基本发现， 工程学科，并加强阿尔伯塔大学和加拿大的地位，作为一个国际领导者， 采矿复垦和油砂尾矿土工技术。
