Abstract

The abandoned Manitou mine site produced acid mine drainage for decades. One of the site's tailings storage facilities (TSF 2) was reclaimed in 2009 using an elevated water table combined with a monolayer cover made of low-sulphur tailings. A field investigation was undertaken from 2012 to 2015 to verify the performance of the reclamation technique in stemming the production of contaminants. This verification is based on two main criteria, i.e., the minimum water table level and maximum oxygen flux reaching the Manitou tailings. Thirteen monitoring stations were installed in TSF 2. The hydrogeological behavior and oxygen migration were investigated at each station by measuring volumetric water content, suction, water table level, gaseous pore oxygen concentration, and oxygen consumption. Analyses of field data showed that the minimum water table level criterion was reached with the exception of a portion of TSF 2 during the summer months. Oxygen fluxes reaching the Manitou tailings were determined using numerical simulations and analytical solutions; their yearly mean was many times lower than maximum targets generally used on reclaimed tailings disposal areas. The current system met the targeted performance criteria over the studied period.Key words: cover, tailings, elevated water table, acid mine drainage (AMD), reclamation.Le site minier abandonne Manitou a produit du drainage minier acide durant des decennies. Le parc 2 ('TSF 2'), l'une des aires de stockage de residus du site, a ete restaure en 2009 avec une nappe surelevee combinee a une couverture monocouche de residus peu sulfureux. Une etude sur le terrain effectuee de 2012 a 2015 visa a evaluer la performance de la technique a limiter la production de contaminants. Cette evaluation est basee sur deux criteres : le niveau phreatique minimum et le flux maximum d'oxygene atteignant les residus Manitou. Treize stations de mesures ont ete installees sur le parc 2. Le comportement hydrogeologique et la migration de l'oxygene ont ete suivis a chaque station a l'aide de mesures de teneur en eau volumique, de succion, de niveau d'eau, de concentration d'oxygene gazeux interstitiel et de consommation d'oxygene. Les resultats ont montre que le critere du niveau phreatique etait atteint, sauf en ete sur une partie du parc 2. Les flux d'oxygene atteignant les residus Manitou ont ete determines a l'aide de simulations numeriques et de solutions analytiques. La moyenne annuelle des flux a ete inferieure a des cibles maximales generalement utilisees. Le systeme actuel a atteint les criteres de performance vises pour la duree de l'etude.Mots-cles : couverture, residus, nappe surelevee, drainage minier acide (DMA), restauration., 1.
