Characterization of Tailing Dams Using Shallow Geophysics: Application in the Cajati B1 Dam, São Paulo

Abstract: Barragens de rejeito são estruturas muito usadas em Mineração. Estas estruturas são monitoradas diariamente por instrumentos como: piezômetros, marcos topográicos e medidores de nível d'água. No Brasil, a utilização de geofísica para avaliação e monitoramento de barragens de mineração não é uma prática usual. A Barragem B1, que faz parte do Complexo Mineroquímico de Cajati (Mosaic Fertilizantes), no estado de São Paulo, foi escolhida para avaliação do uso de eletrorresistividade. O presente trabalho visa discu… Show more

“…The main phenomena that cause erosion are emergence, piping, and saturation of the medium. Traditional inspection methods cannot cover the entire area of interest and do not detect early signs of internal erosion (Albuquerque et al, 2019). Different geophysical methods are already applied to supplement these inspections, such as electrical resistivity (Sjödahl et al, 2008), ground penetration radar (Martini et al, 2016), and seismics (Osazuwa and Chinedu, 2008).…”
