{"title":"Reducing the long term risk and enhancing the closure of tailings impoundments","authors":"A. Adams, C. Hall, K. Brouwer","doi":"10.1201/9780429319778-300","DOIUrl":"https://doi.org/10.1201/9780429319778-300","url":null,"abstract":"Tailings impoundments typically provide long-term storage for saturated, semifluid fine grained materials. Closure of these tailings impoundments represents an ongoing priority and challenge for owners and professionals due to the potential for the impounded tailings to fluidize and flow in the event of a dam failure. This paper provides a case study for the decommissioned Nye Tailings Impoundment at the Stillwater Mine. The closure plan includes capping the loose, saturated tailings with a thick waste rock layer to stabilize the impounded tailings, mitigate potential dusting and provide for water management. Following closure, a Waste Rock Storage Area (WRSA) can be developed on top of the tailings impoundment as part of the final closure cap. This approach would provide for additional waste rock storage within the existing mine disturbance area, thus minimizing the need for additional site disturbance. At the same time, the progressive and controlled placement of waste rock over the capped tailings would enhance the stability of the tailings by promoting additional consolidation induced dewatering and densification. This would reduce the flowability of the tailings, thus reducing the potential consequences of a post-closure dam failure event. RÉSUMÉ : Les parcs de résidus permettent un stockage à long terme pour les matériaux à grain fin saturés et semi-fluides. La possibilité que les résidus enfermés se fluidifient et s’écoulent en cas de brèche du barrage représente une priorité continue et un défi pour les propriétaires et les professionnels pour la fermeture de ces parcs à résidus. Ce document fournit une étude de cas pour la fermeture du parc de résidus de Nye à la mine Stillwater. Le plan de la fermeture comprend le recouvrement des résidus saturés et meubles avec une couche épaisse des roches stériles afin de stabiliser les résidus retenus, d’atténuer la formation de poussière, et de gérer l’eau. Après la fermeture, une zone de stockage de stériles peut être aménagée au-dessus du bassin de retenue des résidus dans le cadre de la couche de fermeture définitive. Cette amélioration permettrait un stockage supplémentaire de stériles dans l’aire de perturbation actuelle des opérations minières, minimisant ainsi le besoin de perturbations supplémentaires du site. En même temps, la mise en place progressive et contrôlée des stériles renforcerait la stabilité des résidus en favorisant la densification et le dénoyage par la consolidation. Cela réduira la fluidité des résidus, réduisant ainsi les conséquences potentielles d’un événement de brèche de barrage après la fermeture.","PeriodicalId":365954,"journal":{"name":"Sustainable and Safe Dams Around the World","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130093942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vuuren","doi":"10.1201/9780429319778-8","DOIUrl":"https://doi.org/10.1201/9780429319778-8","url":null,"abstract":"The Ogee profile is one of the most studied hydraulic relationships used in the design of spillways. The high discharge efficiency and nappe-shaped profile ensure an effective hydraulic system, if applied under the correct conditions. However, in a recent study, the existing Ogee profile relationship, formulated for two-dimensional flow conditions, proved to be insufficient for three-dimensional flow conditions. Data obtained from a detailed physical model study and extensive computational fluid dynamic simulations allowed for a qualitative and quantitative comparison of the bottom nappe of the fluid profile across an aerated sharp-crested weir. The study concluded in the derivation of the VC-Ogee relationship that estimates the Ogee profile under three-dimensional flow conditions. Four parameters A, B, C and D, were incorporated to accommodate the effect of three-dimensional flow. A set of VC-Ogee design curves for these parameters, for an asymmetrical approach channel with side contraction of the spillway, is presented in this paper. Further design curves to accommodate symmetrical, contracted and uncontracted approach channels as well as combinations of these conditions, will be made available in future. RÉSUMÉ: Le profil Ogee est l’une des relations hydrauliques les plus étudiées dans la conception des déversoirs. La haute efficacité d’écoulement et le profil en forme de nappe assurent un système hydraulique efficace s’il est appliqué dans les conditions appropriées. Cependant, dans une étude récente, la relation de profil Ogee existante, formulée pour des conditions d’écoulement bidimensionnelles, s’est avérée insuffisante pour des conditions d’écoulement tridimensionnelles. Les données obtenues à partir d’une étude de modèle physique détaillée et de simulations informatiques exhaustives de la dynamique des fluides ont permis une comparaison qualitative et quantitative de la nappe inférieure du profil de fluide à travers un déversoir élevé à crête pointue aéré. Ces études ont permis de dériver la relation « Ogee VC » qui comprend des déversoirs droits et courbes, des canaux d’approche symétriques et asymétriques, ainsi que des déversoirs contractés et non contractés. Quatre paramètres A, B, C et D ont été incorporés pour tenir compte de l’effet du débit tridimensionnel. Cet article présente un ensemble de courbes de conception VC-Ogee pour ces paramètres, pour un canal d'approche asymétrique avec contraction latérale du déversoir. D'autres courbes de conception permettant d'adapter des canaux d'approche symétriques, contractés et non contractés, ainsi que des combinaisons de ces conditions, seront disponibles à l'avenir.","PeriodicalId":365954,"journal":{"name":"Sustainable and Safe Dams Around the World","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129313520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
