ABSTRACT: The Quemont 2 mine site, located near the Rouyn-Noranda city, covers an area of 119 hectares and its reclamation should be performed during the next few years after tailings storage facilities (TSF) closure. To select the appropriate reclamation technic for controlling acid mine drainage (AMD), three-dimensional numerical groundwater was built and calibrated with the objective to simulate the hydrogeological behavior of the mine site after TSF closure. After model calibrations, the model was completed by considering the impact of climate change on water resources of the TSF. In these last simulations, the effect of climate change in Quemont 2 will be the increase of the groundwater level due to the precipitation increase. These results will be used in the next step to evaluate the cover performance placed on the TSF of the Quemont 2 mine site.


RÉSUMÉ: Le site minier Quemont 2, situé près de la ville de Rouyn-Noranda, couvre une superficie de 119 hectares et sa réhabilitation devrait être effectuée au cours des prochaines années après la fermeture des installations de ce parc. Afin de sélectionner la technique de réhabilitation appropriée pour contrôler le drainage minier acide (DMA), un modèle numérique tridimensionnel des eaux souterraines a été élaboré et calibré dans le but de simuler le comportement hydrogéologique du site minier. Après ces calibrations, le modèle a été complété en considérant l'impact du changement climatique sur les ressources en eau de ce site. Dans ces dernières simulations, l'effet du changement climatique sur le Quemont 2 sera l'augmentation du niveau des eaux souterraines due principalement à l'augmentation des précipitations. Ces résultats seront utilisés dans la prochaine étape pour évaluer la performance de la couverture mise en place sur l'ISR du site minier Quemont 2.
