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.

Written by civil engineers, dam safety officials, dam owners, geologists, hydraulic engineers, and risk analysts, this handbook is the first cooperative attempt to provide practical solutions to dam problems within the financial constraints faced by dam owners. It provides hands-on information for identifying and remedying common defects in concrete and masonry dams, embankment dams, reservoirs, and related structures. It also includes procedures for monitoring dams and collecting and analyzing data. Case histories demonstrate economical solutions to specific problems.

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.

The purpose of the inspection was to assess the general condition of the dam with respect to safety. The assessment was based on an evaluation of the available data, a visual inspection and an evaluation of the hydrology and hydraulics of the site to determine if the dam poses hazards to human life or property. The purpose of the dam is to impound lead tailings. Inspection and evaluation indicated that the combined capacity of the spillway and 48-inch diameter concrete outlet does not meet the criteria given in the Guidelines for a dam of the size and hazard potential of Main Tailings Dam. As a small dam with a high hazard potential, it is required by the Guidelines to pass to 50 100 percent of the Probable Maximum Flood (PMF) without overtopping the crest. The spillway design flood adopted for this dam is 100 percent of the PMF because the consequences of failure are serious since the dam is located about 1/4-mile from a residential area of Fredericktown. The PMF is the flood that maybe expected from the most severe combination of critical meteorologic and hydrologic conditions that is reasonably possible in the region. It was calculated that the spillway and outlet could pass a 100-year flood (a flood having a 1 percent change of being equalled or exceeded in any 1 year) without overtopping the dam.

Tailings are the residue of the milling process for extracting metals for ore. They are mostly commonly dumped in surface impoundments (tailing dams), the embankments of which are usually earthfilled dams. In spite of a number of guidelines to their design and construction there are still major failings each year. This book gathers together 221 case records of incidents in attempt to investigate the causes of failure. The main causes were found to be lack of control of water balance, lack of control of construction, lack of understanding of the feature that control safe operation
