New database to help mining companies predict behavior of tailings flows


Researchers led by a team at the University of Waterloo created a database as part of a study that presents the first global picture of the occurrence rates, behaviors and physical impacts of tailings flows, which are rapid downstream movements of mine waste following the failure of tailings dams. 

The study, which was published in the journal Engineering Geology, involves researchers in three Canadian provinces and reports detailed information on 63 tailings flows that have occurred worldwide since 1928. 

According to the review, catastrophic tailings flows have happened once every two to three years on average since 1965, causing death, long-lasting environmental contamination and severe infrastructure damage over distances that can span tens of kilometers. Hazardous weather and inadequate drainage systems have been the most frequent triggers for tailings flows since 1996.
