Modelling the Brumadinho tailings dam failure, the subsequent loss of life and how it could have been reduced

Abstract. In recent years the number of tailings dams failures has increased. On 25 January 2019, Brumadinho dam in Brazil suddenly failed, releasing a mudflow over 10 m deep comprising some 107 m3 mining waste which killed between 270 and 320 people. This paper details use an agent-based model, known as Life Safety Model (LSM), to estimate risk people downstream assess if fatalities could have been reduced warning had received prior or at time failed. The LSM modelling indicates that even issued reduced. Agent-based tools such can help inform improve emergency plans for dams, will reduce risks posed by them future.
