100 years 289 tailings dams failures history is the result brought in by a very detailed research (www.csp2.org) including a freely downloadable database and several explanatory and interpretative papers by Bowker and Chambers. 100 years 289 tailings dams failures history The database contains (on October 7th 2016) 289 failures occurred in 2016-1915= 101 years. Additionally the database contains all reported, failures in the period, from irrelevant/small released volumes, short runout distances, no victims, to the recent large failures (Mount Polley…
