The comparison of ORE2_Tailings estimated dam failure probabilities is an important element of Riskope continued commitment to test the validity of the approach. Quantitative risk assessment in tailings One can perform a Quantitative Risk Assessments (QRA) using various methods. Indeed, for tailings dam risks, they all consist in evaluating the: probability of failure of the dam generated by various pertinent hazards, potential consequences of a dam system collapse (failure) and finally the risk. The technical and mathematical tools for performing…

Mount Polley Dam Breach: discussing Tailings Dam Failure Frequency and Portfolio Risk. Continued Mount Polley Dam Breach: discussing Tailings Dam Failure Frequency and Portfolio Risk. Continued. The mandate given to the expert panel forced them to consider all failures “equal”. Thus the risk equation became the simple expression of the probability of failure. We have discussed how tolerance and risk engineering would apply to large portfolios of dams and other critical infrastructures. We also expressed our opinion in the aftermath…

Mount Polley Dam Breach: discussing Tailings Dam Failure Frequency and Portfolio Risk We have read the recent Report on Mount Polley Tailings Storage Facility Breach by the Independent Expert Engineering Investigation and Review Panel, and we are discussing below the Appendix I: B.C. Mount Polley Dam Breach: discussing Tailings Dam Failure Frequency and Portfolio Risk Defining what constitutes a failure The Appendix looks at dam failures where “failure is defined as breach of the dam resulting in release of tailings…
