Book excerpt: Post-closure tailings dams are expected to remain on mine sites in perpetuity following mine closure. Combined with the lack of knowledge regarding how tailings dams will evolve over time, these long-time frames necessitate the development of risk management practices. The purpose of this research was to develop methodology to support the process of determining and assessing the long-term risks of tailings dams in Alberta as they transition into landforms. The research project evaluated the state of knowledge on the long-term behaviour of tailings dams and demonstrated the knowledge gap (and associated uncertainty) associated with the closure phase of a tailings dam. To address this, a risk management tool, referred to as the Generalized Failure Modes Effects Analysis (G-FMEA) framework, was developed. The G-FMEA framework was applied to a case study oil sands tailings dam to illustrate an example application for practitioners. Finally, seepage analysis was conducted on the case study oil sands tailings dam to demonstrate how modelling tools can be used in conjunction with risk management tools to reduce uncertainty. To aid in the development of the G-FMEA framework, a detailed literature review and interviews with industry professionals were conducted. This process allowed for available information on the physical performance of tailings dams undergoing closure in Canada to be synthesized. Further, it allowed for the identification of hazards, triggers, failure modes, and uncertainties associated with tailings dam closure, which was a key element to the G-FMEA development. The interviews themselves clearly showed the lack of consensus amongst practitioners regarding long-term dam evolution. This emphasizes the uncertainty associated with closure and is a primary reason why comprehensive risk management practices must be developed. The developed G-FMEA framework uses an element approach to conduct the FMEA, which allows for the relationships between different elements to be established. The G-FMEA framework includes four individual charts for the drainage system, foundation, dam body, and landform to assess the failure modes, triggers/causes, and failure effects for different elements. The G-FMEA framework requires the risk assessment to be conducted at four different temporal scales (immediate term, short term, medium term, and long term) that are anchored to different periods of management of the facility. A risk matrix was developed for use with the G-FMEA, which includes a likelihood rating table, consequence rating table, and risk rating table. The developed G-FMEA framework provides a systematic method to assess the risks following closure of tailings dams. The G-FMEA framework was applied to a case study oil sands tailings dam to illustrate how the framework could be used in practice. Two example failure modes were selected to show how the risk matrix could be used to assign risk ratings. For both of the example failure modes, the risk rating increased as the temporal scale increased, which is partially attributed to the increasing uncertainty over time. Long-term seepage modelling was conducted on a case study oil sands tailings dam to evaluate how the phreatic surface may evolve in response to various factors (drain failure, pond formation, downstream slope erosion, and climate change). The results suggest that the phreatic surface has the potential to rise in the long term in response to different events, including drain failure and ponds forming on the reclamation surface. The seepage modelling was used to show how modelling could be used to inform risk management decisions by reducing uncertainty and allowed for the development of a framework for guidance on conducting long-term seepage modelling.
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.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers a timely report on methods for risk assessment procedures for dams, with a special emphasis on dams with small storage dimensions. It starts by introducing all important definitions relating to dams, dam safety, such as the most common failure modes, and risks. In turn, it describes in detail the most important evaluation procedures for various failure modes such as piping, flood, earthquake and stability are described in this chapter. Consequence assessment procedures, together with the different steps of the risk evaluation process, are analyzed, providing a guide on how to identify the appropriate failure mode for the examined dam and setting up the appropriate safety plan. The book introduces the most common methods for predicting peak breach discharge, analyzing some relevant case studies. Upon comparing the findings obtained with the different methods, the book concludes with some general suggestions and ideas for future developments. This book fills an important gap between theoretical works and real-life problems being investigating in practical research studies on dam safety and risk management. It provides readers with the necessary knowledge on risk analysis and shows how to apply this in practice to carry out dam safety studies. It offers practical guidelines to set up risk assessment procedures for different failure modes and predicting failure parameters such as failure time, peak breach discharge and breach width.

Available in PDF, EPUB and Kindle. Book excerpt: Dam safety is central to public protection and economic security. However, the world has an aging portfolio of large dams, with growing downstream populations and rapid urbanization placing dual pressures on these important infrastructures to provide increased services and to do it more safely. To meet the challenge, countries need legal and institutional frameworks that are fit for purpose and can ensure the safety of dams. Such frameworks enable dams to provide water supplies to meet domestic and industrial demands, support power generation, improve food security, and bolster resilience to floods and droughts, helping to build safer communities. Laying the Foundations: A Global Analysis of Regulatory Frameworks for the Safety of Dams and Downstream Communities is a systematic review of dam regimes from a diverse set of 51 countries with varying economic, political, and cultural circumstances. These case studies inform a continuum of legal, institutional, technical, and financial options for sustainable dam safety assurance. The findings from the comparative analysis will inform decisionmakers about the merits of different options for dam safety and help them systematically develop the most effective approaches for the country context. By identifying the essential elements of good practices guided by portfolio characteristics, this tool can help identify gaps in existing legal, institutional, technical, and financial frameworks to enhance the regulatory regime for ensuring the safety of dams and downstream communities.

This book was released on 2022-02-01 with total page 1026 pages. Available in PDF, EPUB and Kindle. Book excerpt: As long as we have mining and mineral processing, tailings and the responsible management thereof will remain at the forefront, with a company’s environmental, social, and governance (ESG) performance in part a reflection of how well tailings risks are being managed. The Global Industry Standard on Tailings Management (GISTM) was published in August 2020, aiming to prevent catastrophic failure of tailings facilities by providing operators with specified measures and approaches throughout the mine life cycle, taking into account multiple stakeholder perspectives. In 2021, the International Council on Mining & Metals (ICMM) published the Tailings Management: Good Practice Guide intended to support safe, responsible management of tailings across the global mining industry, providing guidance on good governance and engineering practices to support continual improvement in tailings storage facility (TSF) management and help foster and strengthen the safety culture of mining companies. The Tailings Management Handbook is important and timely because there is no other comprehensive resource rooted in these new fundamentals and global principles for tailings management. Tailings management requires interdisciplinary and cross-functional understanding and support, which is apparent throughout this handbook. Dive into the wealth of information contributed by more than 100 world-renowned experts, beautifully crafted into a full-color handbook that focuses on the basics, life-cycle planning, site and tailings characterization, TSF design and construction, as well as systems and operations of TSFs. The inclusion of 42 case studies is an added plus with real-world successes and lessons learned.

Download or read book Dam and Levee Safety and Community Resilience written by National Research Council and published by National Academies Press. This book was released on 2012-10-11 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although advances in engineering can reduce the risk of dam and levee failure, some failures will still occur. Such events cause impacts on social and physical infrastructure that extend far beyond the flood zone. Broadening dam and levee safety programs to consider community- and regional-level priorities in decision making can help reduce the risk of, and increase community resilience to, potential dam and levee failures. Collaboration between dam and levee safety professionals at all levels, persons and property owners at direct risk, members of the wider economy, and the social and environmental networks in a community would allow all stakeholders to understand risks, shared needs, and opportunities, and make more informed decisions related to dam and levee infrastructure and community resilience. Dam and Levee Safety and Community Resilience: A Vision for Future Practice explains that fundamental shifts in safety culture will be necessary to integrate the concepts of resilience into dam and levee safety programs.

Download or read book Mine Tailings written by Resa Furey and published by Society for Mining, Metallurgy & Exploration. This book was released on 2020-12-16 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Re-imagine the Future of Tailings Nearly every recent article on tailings starts by mentioning a large tailings dam failure. The consequences of these failures have been so devastating they have pushed conversations about the risks inherent in these structures beyond the mining community into the general population. We are left to question how we address the risks associated with tailings disposal, and in so doing, transform the image of the mining industry and perhaps the industry itself. With this as a backdrop, the Society for Mining, Metallurgy & Exploration (SME) challenged tailings and mining professionals to re-imagine the future of tailings. The Mine Tailings: Perspectives for a Changing World symposium, held at the SME 2020 annual conference, started that conversation. Over three days, tailings professionals from around the world gathered to discuss tailings storage practices and the changes both the industry and the world want and need. The discussions squarely focused on how we, as an industry, can collectively make changes that will eliminate catastrophic tailings dam failures and lead to better outcomes for the industry and society. Through sharing and conversation, the symposium participants recognized risks associated with our approach to tailings management and existing structures and discussed the gaps that need to be addressed, including how the behavior of tailings and mining professionals must change. The human element of risk must be recognized so it can be talked about openly, given the attention it deserves, and adequately addressed. We need to own this problem and the impact of our actions. We have the power to change this; when we own our actions, we can act differently for a different outcome.
