Management of tailings in the oil sands industry contintues to be a challenege both economically and from an environmental perspective. Many developing technologies appear to be promsing to reduce environmental impacts and to facilitate recalamation of tailings sites and ecological respotration, but substantial room for increasing technical performance and finding cost efficiencies remains. Recent regulatory changes and industry outlook have re-directed priorities towards longer term low cost solutions to dewatering fines grained tailings and facilitiate closure and ecological restoration of tailings ponds over the mine lifetime (20 to 30 year outlook), rather than high cost solutions that target short-term goals. Technically, this leads to a need to better understand the natural long term (months to years) dewatering behaviour of new tailings technologies, which is the scientific focus of the proposed project. The project will develops new measurement devices and techniques for evaluating the long-term dewatering behaviour of oil sands fine tailings.******

从经济和环境的角度来看，油砂行业的尾矿管理仍然是一个挑战。许多发展中的技术似乎有望减少对环境的影响，并促进尾矿场址的复垦和生态呼吸，但仍有很大的空间提高技术性能和寻找成本效益。最近的监管变化和行业前景重新将优先事项转向长期低成本解决方案，以脱水细粒尾矿，并在矿山生命周期（20至30年展望）内促进尾矿库的关闭和生态恢复，而不是针对短期目标的高成本解决方案。从技术上讲，这导致需要更好地了解新尾矿技术的自然长期（数月至数年）脱水行为，这是拟议项目的科学重点。该项目将开发新的测量设备和技术，以评估油砂细尾矿的长期脱水行为。******
