ABSTRACT: A crucial challenge of mining industry is to minimize the environmental impact of tailings. The co-disposition of tailings and waste rock was proposed, with the waste rock forming rigid and permeable inclusions within the tailings mass, to improve the overall performance of the impoundment. The RIME UQAT-Polytechnique, Canadian Malartic Mine, Golder Associés and other industrial partners are conducting a comprehensive, research project to quantify the effects of inclusions in tailings impoundments and to develop guidelines for their general use. The project is focused on the tailings impoundment of the Canadian Malartic Mine, which contains waste rock inclusions. The research project includes field monitoring and instrumentation, in situ testing, conventional and specialized laboratory testing, physical modelling and numerical simulations. This paper presents an overview of the research project and some preliminary findings.
RÉSUMÉ: Un défi important minière est de minimiser l'impact environnemental des parcs à résidus. La co-disposition des résidus et des stériles a été proposé avec les stériles utilisés comme inclusions rigides et perméables dans les résidus comportement général des parcs à résidus. UQAT-Polytechnique, la mine Canadian Malartic, Golder Associés et autres partenaires industriels mènent un projet de recherche pour évaluer des inclusions sur le comportement d'un parc à résidus et élaborer des lignes directrices pour l'utilisation général des inclusions. Le projet se concentre sur les inclusions de roches stériles du parc à résidus de la mine Canadian Malartic. Le projet de recherche comprend un suivi sur le terrain, une instrumentation du site, les essais in situ et de laboratoire conventionnels et spécialisés, une modélisation physique et des simulations numériques. Cet article résume le projet de recherche et montre quelques résultats préliminaires.
