Synopsis of the Talk

This presentation aims to show, how the risk-based approach to the safety review of tailings dams can help dam owners keep societies safe and efficiently protect their assets also their reputation.

Risk-based assessment is a powerful tool to assess the safety of tailings dams by focusing on credible failure scenarios which will help identify risks, prioritise the required actions and eventually mitigate the risks in an efficient and cost-effective way. The main advantage of this method compared to the traditional standards-based assessment is the prioritisation of the risk mitigation options based on the risks associated with different failure modes.

The presentation will introduce quantitative piping risk assessment, based on the piping toolbox, a unified method for estimating probabilities of failure of embankment dams by internal erosion and piping. This method has been developed collectively by the University of NSW, URS, US Army Corps of Engineers, and US Bureau of Reclamation.

A risk-based safety assessment including the quantitative piping assessment will be presented as a case study. This case study addresses the risks to society and suggests several practicable risk mitigation options. The estimated risks for all loadings and failure modes considered are expressed as F-N plots representing the level of Societal risk and the implication of the ALARP Principal and mitigation options are discussed.
