NSERC-UQAT Industrial Research Chair on mine site reclamation

在过去二十年左右的时间里，采矿业在开发工具和技术方面投入了大量资金，以改善废石和尾矿的管理。然而，尽管取得了这一进展，但仍有一些重要领域需要研究，特别是在回收含有可产生受污染的矿井废水的活性矿物的矿山废物处置区方面。这项研究计划的长期目标是制定有效的填海战略，利用新的方法或技术限制对环境的影响和风险。拟议的研究包括五个项目：1)与矿场复垦有关的理论方面；2)尾矿储存设施的复垦；3)废石储存设施的复垦；4)工程矿盖的长期性能；5)技术和知识转移。拟设主席将综合使用调查方法，包括实验室测试、物理建模、现场测量和监测以及数值模型的开发和应用。这一工业席位将允许开发新技术和/或改进现有技术，以回收位于不同气候条件的硬岩矿山的矿山废物处置区。规划开垦战略正变得越来越重要，甚至在项目的早期阶段也是如此，在该项目中，必须让当地社区相信，拟议的地雷不会成为环境问题。该主席的工作将通过培训高素质人员来开展，这些人员将成为急需的专家，帮助采矿业生产金属，同时减少其对环境的影响。

Over the past twenty years or so, the mining industry has invested significant capital in the development oftools and technologies for improving the management of waste rocks and tailings. However, despite thisprogress, there are still important areas that need to be studied, particularly with respect to the reclamation ofmine waste disposal areas containing reactive minerals that can generate contaminated mine drainages. Thelong-term objective of this research program is to develop efficient reclamation strategies that limitenvironmental impacts and risks using novel approaches or technologies. The proposed research includes fiveprojects: 1) Theoretical aspects related to mine site reclamation; 2) Reclamation of tailings storage facilities; 3)Reclamation of waste rock storage facilities; 4) Long-term performance of engineered mine covers; and 5)Technology and knowledge transfer. The proposed Chair will use a combination of investigative approaches,including laboratory testing, physical modeling, in situ measurements and monitoring, and numerical modeldevelopment and application. This industrial chair will allow for the development of new technologies and/orthe improvement of existing technologies for reclaiming mine waste disposal areas at hard rock mines that arelocated in varied climatic conditions. The planning of reclamation strategies is becoming increasingly crucial,even during the early stages of a project in which local communities must be convinced that a proposed minewill not become an environmental problem. The work in this Chair will be performed through the training ofhighly qualified personnel who will become much-needed specialists that will help the mining industry producemetals while reducing their environmental impacts.
