One of the critical challenges facing the mining sector is related to the prevention and mitigation of catastrophic incidents associated with its tailing dams. As mining tailings are very heterogeneous and field characterization is expensive and comp

[pt] O monitoramento de barragens de rejeito, essencial para prevenir acidentes, se baseia em inspeções visuais e instrumentação geotécnica. Devido a recentes incidentes, o aprimoramento tornou-se crucial, levando à incorporação da geofísica
[pt] A ocorrência de dois acidentes de proporções inaceitáveis no Brasil, num período de 4 anos, resultou em problemas de confiança nos projetos e na operação de barragens de rejeitos, em especial as construídas pelo método de montante. Ess

Abstract This paper proposes the use of a hybrid method that combines Biased Random Key Genetic Algorithm (BRKGA) with a local search heuristic to separate Brazilian tailing dam data into groups. The goal was identifying dams similar to Fundão and B

The disaster-causing mechanism of unstable tailing dams is extremely complex. However, the impact of multi-scale and multi-factor mechanical properties of railings is not adequately considered in existing studies on the disaster prevention of tailing
