Metodologia Para Verificação De Volumes De Bacias De Rejeito De Mineração Por Geoprocessamento – Barragem De Maravilhas Ii (Quadrilátero Ferrífero-Mg)

Abstract: Após o rompimento da barragem de Fundão em Mariana-MG, da mineradora Samarco em novembro de 2015, as atenções se voltaram para a necessidade de um melhor conhecimento e controle das demais barragens de rejeito de mineração. Uma das formas de se investigar eventuais irregularidades dessas estruturas, que se localizam em vales de bacias hidrográficas, é verificar se os volumes declarados pelas mineradoras para as suas bacias de rejeito realmente correspondem às informações prestadas nos respectivos processos de … Show more

“…Its major impacts occur due to the construction of tailings dams, the concession of mines licenses, and the lack of commitment to restoring degraded areas. Leading to the fragmentation of forest areas and results in the lowering of groundwater, alteration of slope in mined areas, and the decrease in the flora and fauna diversity (Camargos et al 2019;Rezende, 2016). However, these activities also provide uncountable social, economic, cultural, and environmental benefits, such as employment generation, poverty reduction, and public education improvement.…”
