中文摘要
在阿萨巴斯卡地区扩大油砂业务带来的经济机会是巨大的,但沥青开采过程的副产品也是如此。在景观修复方面具有特别重要的环境意义的是尾矿管理,更具体地说,是将关闭的矿坑用作尾矿库盆地的可能性。为了让这些所谓的尾矿湖(EPL)成为可接受的处置替代方案,尾矿必须覆盖一个淡水层,随着时间的推移,这个淡水层会发展成一个自我维持的生态系统。事实上,生态系统的成熟预计将与尾矿脱水同时发生,从而使EPLs成为北方针叶林的自然组成部分。
英文摘要
The economic opportunities associated with expanded oil sands operations in the Athabasca region are substantial, but so too are the by-products of the bitumen extraction process. Of particular environmental importance in the context of landscape remediation is tailings management, more specifically the possibility of using closed mine pits as tailings repository basins. In order for these so-called end-pit lakes (EPLs) to represent an acceptable disposal alternative, tailings must be capped with a fresh water layer that, over time, develops into a self-sustaining ecosystem. Indeed ecosystem maturation is expected to occur simultaneously with tailings dewatering so that EPLs become a natural component of the boreal forest.
