Résumé - Abstract:

At approximately 12:28 pm local time on January 25, 2019, tailings dam B-1 at Vale S.A.’s Corrego do Feijao Iron Ore Mine, located 9 kilometers north-east of Brumadinho, in the state of Minas Gerais, Brazil, suffered a sudden failure resulting in a catastrophic mudflow that travelled rapidly downstream resulting in significant damage and the loss of over 250 lives. This failure was unique in that there are high quality video images of the event that provide insight into the failure mechanism. This presentation will provide a summary of the Expert Panel investigation carried out to determine the technical causes of the failure.
