Abstract

Public concern over safety of tailings dam facilities is growing as recent tailings dam failures in British Columbia (Canada) in 2014, Buenavista del Cobre, Sonora (Mexico) in 2014 and Bento Rodrigues (Brazil) in 2015, have resulted a significant impact to people and the environment. Breaching of tailings dams often results in the sudden release of water and sediments (tailings).  These recent events, while highly publicized, are not isolated or particularly unique occurrences.  Global record of historical events shows that consequences following these failures have been significant and in some instances catastrophic. Consequences of historical events included loss of life, changes in fluvial geomorphology and slope stability, widespread contamination resulting in loss of terrestrial and aquatic habitat, as well as legal repercussions and lack of public confidence.  This presentation will give an overview of several case studies, the empirical statistics of tailings dam failures as well as the root causes of failure.  Finally, the author will present some thoughts on the state of practice, our responsibilities as practitioners, and some lofty goals for the future.
