Best Practices for Tailings Dam DesignSep 07, 2017 · Background. Recent major tailings dam failures have led to an industrywide review of the design and management of tailings storage facilities. Before the 1960s, mine tailings were often disposed directly into ponds, lakes, rivers or natural topographic depressions, or stored in impoundments supported by earthen dams, without necessarily applying engineering principles (McLeod et al. 2015).
