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.

Mining has evolved in the 21st century into an indispensable industry that provides a variety of mineral products needed to sustain a modern society. To achieve efficiency, it has also grown into an integrated enterprise of enormous size, wielding substantial economic power. Tailings is essentially a fine-particle mine-waste byproduct. Its management has gone through major transformations in the last century. In early years tailings was disposed of out of sight and literally out of mind. However, due to the physical and chemical characteristics of tailings, this laissez-faire approach in dealing with its disposal led to significant environmental degradation such as pollution and blockage of watercourses, etc. With the rising environmental protection movement, the mining operation is under increasing regulatory constraints and governmental monitoring. Modern tailings dams have become major hydraulic structures designed, constructed, monitored until they are properly closed and reclaimed after the completion of mining tenure. These dams are often higher than 100 m, with a storage capacity of over hundreds of million cubic metres, serving a vital industrial function for the public. Unfortunately, when such a dam fails, it unleashes enormous destructive power causing inundation of water and tailings mud over the downstream area resulting in fatalities and lasting environmental degradation. This book presents a condensed monograph on forensic investigations of select case histories of failed tailings dams. The selection tends to emphasize recent cases that have representative characteristics including those affecting the evolution of the current practice of tailings dam engineering. Efforts are made to facilitate readers’ understanding of important factors involved by using plain language. Technical terms are clearly explained before their usage. The objective of the monograph is to provide a neutral reference on tailings dam failures for all stakeholders. The author hopes ongoing dialogues by all stakeholders on the important topics of dam safety will raise the safety standard of tailings dams to a new level compatible with public expectations of the sustainable mining industry.

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

Since the dawn of civilization, the majority of basic human needs have been obtained from mines. The rapid growth of population and the increase in need of mining activities accordingly have led to a rise in the amount of waste products (i.e. mine tailings). There have been 46 tailings dam failures around the world over the last two decades and this figure has been rising continuously. Among various reasons for tailings dam failure, the undrained failure in underlying fine-grained soils is considered to be one of the major contributing factors. In this study, an attempt was made to estimate the stability of a tailings dam in Elkview Operations (EVO) located approximately three kilometers east of Sparwood in the southeastern part of British Columbia. For this, a series of numerical analyses were performed using finite difference software (FLAC3D) to predict effective stress path in the underlying clayey silt layer, considering staged construction under undrained condition. The behavior of clayey silt layer under each construction stage was estimated by adopting the Modified Cam-Clay constitutive model. The factor of safety was then computed based on the critical state line and effective stress path. The analysis results showed that additional deposition of tailings can lead to a failure in the tailings dam, which can be initiated from zones below the toe of tailings dam. The sensitivity analysis results showed that the slopes of critical state and normal consolidation lines are the most influential parameters to the stability of tailings dam.
