ORE2-Tailings allow benchmark of tailings dams probability of failure

Today we discuss how ORE2-Tailings allow benchmark of tailings dams probability of failure. The considered mine for this case history has a portfolio of 15 dams. The figure below shows in the vertical axis the annual Probability of failure (pf) results under the form of yellow vertical bars. The extreme of the bars represent the minimum and maximum estimates of the probability of failure for each dam. Hence, the length of the bars measures the uncertainty on the evaluation of…
