Floods from tailings dam failures - ScienceDirect

Jun 15, 2008 · With tailings dams, empirical relationships are very limited probably due to the scarcity of reliable historical data. Lucia et al. proposed a method to estimate the potential mine waste run-out distance (at slopes <4°), based on historical tailings dam failures and using the value of the residual strength of liquefied tailings. Although these ...
