Available in PDF, EPUB and Kindle. Book excerpt: Tailings are produced from the processing of mineral ores and are commonly stored within embankment dams. The design of the dams requires application of sound engineering principles and an understanding of the properties of the tailings. This Bulletin provides a framework for classifying different types of tailings, ranging from ultra-fine to coarse, based on their geotechnical properties and provides typical geotechnical parameters for the different tailings types. Technologies for dewatering tailings to reduce the risk of storage continue to be developed and the different technologies, from thickening to filtration, and re-application of old technologies are presented to illustrate the options available and, where appropriate, typical in situ properties. This bulletin is directed towards a wide audience of stakeholders: designers, owners, regulators, communities and various organizations and provides a reference for communicating tailings properties and the benefits and limitations of technologies. All mining operations, and thereby tailings operations, are unique. There is no one-solution-fits-all. Tailings dam designs need to account for site-specific conditions, such as climate, physiography, geochemistry, geomorphology, seismology, mining processes, environment, and community setting, with the application of technologies playing an important role in developing safe, sustainable tailings facilities. Les stériles miniers sont produits à partir du traitement des minerais et sont généralement stockés derrière des barrages en remblai. La conception des barrages nécessite l'application de principes d'ingénierie solides et une compréhension des propriétés des résidus. Ce bulletin fournit un cadre pour classer différents types de résidus, allant de l'ultra-fin au grossier, en fonction de leurs propriétés géotechniques et propose des paramètres géotechniques typiques pour les différentes sortes de résidus. Les technologies d'assèchement des résidus pour réduire le risque de stockage continuent à être développées ; les différentes technologies, de l'épaississement à la filtration, en passant par l’application des anciennes technologies, sont présentées pour illustrer les options disponibles et, le cas échéant, les propriétés in situ typiques. Ce bulletin s'adresse à un large public d'intervenants : concepteurs, propriétaires, régulateurs, communautés et organisations diverses et fournit une référence pour communiquer les propriétés des résidus et les avantages et les limites des technologies. Toutes les opérations minières et, par conséquent, les traitements des résidus, sont uniques. Il n'y a pas de solution unique pour tous. La conception des barrages de résidus doit tenir compte des conditions propres au site, telles que le climat, la physiographie, la géochimie, la géomorphologie, la sismologie, les processus miniers, l'environnement et le milieu communautaire, l'application de technologies jouant un rôle important dans le développement de parcs à résidus sûrs et durables.
Download or read book Tailings Dam Management for the Twenty First Century written by Franco Oboni and published by Springer. This book was released on 2019-07-13 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive approach to address the need to improve the design of tailings dams, their management and the regulation of tailings management facilities to reduce, and eventually eliminate, the risk of such facilities failing. The scope of the challenge is well documented in the report by the United Nations Environment Program (UNEP) and GRID Arendal entitled “Mine Tailings Storage: Safety Is No Accident,” which was released in October 2017. The report recommends that “Regulators, industry and communities should adopt a shared, zero-failure objective to tailings storage facilities...” and identifies several areas where further improvements are required. In this context, the application of cutting-edge risk-assessment methodologies and risk-management practices can contribute to a significant reduction and eventual elimination of dam failures through Risk Informed Decision Making. As such, the book focuses on identifying and describing the risk-assessment approaches and risk-management practices that need to be implemented in order to develop a way forward to achieve socially acceptable levels of tailings dam risk.

Book excerpt: "Mine tailings dams are geotechnical structures that are designed to provide adequate and safe storage of tailings materials both during and after the end of mine life. The design of tailings dams is currently based on limit equilibrium methods (LEM) which are used to calculate slope stability safety factors under various operational loads. The minimum safety factor obtained from these analyses is retained to be the design safety factor. LEM's however suffer from a number of shortcomings most notably the lack of information on dam deformation and the interaction between effective stress and pore pressure. For this, advanced numerical modeling techniques accounting for the hydro-mechanical coupling occurring in the dam structure have been developed. These models provide much greater insight into the geotechnical behavior of the tailings dam. However, both LEM and numerical modeling approaches are deterministic in nature; thus, they do not take into consideration the inherent uncertainty of the construction material properties -- a fact that is well known to the geotechnical engineer, yet, needs to be addressed.In this thesis, stochastic analysis approaches such as the Monte Carlo (MC) method are adopted to investigate the effect of the inherent uncertainty in material properties on the design factor of safety. Both LEM and coupled hydro-mechanical numerical models are first developed and the results for deterministic models are compiled. These are then compared with the result obtained from stochastic analyses. A case study of a new water retention tailings dam project design with well documented geotechnical data is adopted throughout the thesis study. First the LEM analysis was pursued followed by a sensitivity analysis to determine the most influential parameters on the design safety factor. Next, a fully coupled hydro-mechanical model was developed with FLAC2D in which the construction sequence was simulated in seven stages. The factor of safety (FOS) was calculated at the end of every stage using the Strength Reduction Technique (SRT). Following that, the Point Estimate Method (PEM) was then used to obtain the probability of unsatisfactory performance by considering the dam's core angle of friction, cohesion and permeability as stochastic variables. The coefficient of variation for the material properties was varied and its consequence on the probability was recorded. Next, the MC method was adopted to calculate the tailings dam's probability of unsatisfactory performance as well as its reliability. The effect of changing the probability density function (PDF) of the stochastic input parameter on the output reliability was further analyzed. Furthermore, the effect of randomness at the local level was studied using the Random Monte-Carlo (RMC) method and compared to the output of the MC method.Finally, the effect of the coefficient of correlation between the dam's core angle of friction and its cohesion on the impoundment's reliability was analyzed. This was followed by an advanced stochastic analysis using the MC method that included a third stochastic variable, the dam's core permeability. The incorporation of both mechanical and hydraulic parameters as stochastic variables lowered the impoundment's reliability; thus, highlighting the power and novelty in the hydro-mechanical stochastic analysis hybrid approach. The results of all analyses are presented in the thesis along with the findings in the conclusion." --
