    • Effects of tailings viscosity on liquefaction triggering analyses 

      Mánica Malcom, Miguel Ánge; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (University of Alberta, 2021)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Recent analyses have suggested that creep or rate effects may be present in some tailings and can play a role in triggering liquefaction failure. However, the role of creep in liquefaction triggering analysis of tailing ...

    • Exploring viscous effects on numerical simulations of static liquefaction triggering 

      Pinedo Vilcahuamán, Paul José; Besenzon, Davide; Mánica Malcom, Miguel Ángel; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (Gecamin, 2022)

      Failures due to static liquefaction have been too frequent in tailings dams. Stress-deformation numerical analyses based on critical state theory are able to reproduce those failures and may be used to gain insight into ...

    • Influence of the particle size distribution on the Critical State Properties of Mine Tailings 

      Vergaray, Luis; Macedo, Jorge; Cody, Arnold; Arroyo Alvarez de Toledo, Marcos (University of British Columbia (UBC), 2022)
      Text en actes de congrés
      Accés obert
      Arguably, critical state soil mechanics (CSSM) is now the preeminent methodology for understanding static liquefaction of mine tailings, having been used in the mining industry by the expert panels retained to investigate ...

    • La rotura de la presa de relaves de Brumadinho: la montaña de cristal 

      Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (2022)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      En Enero de 2019 en Brumadinho (Brasil) una presa de relaves mineros de gran tamaño colapsó en su totalidad de forma brusca, causando la muerte a 270 personas y una gran conmoción en la minería mundial. La rotura fue ...

    • Tailings desiccation process studied in environmental chamber experiment 

      Garino Libardi, Lucas Martín; Oldecop, Luciano Agustín; Romero Morales, Enrique Edgar; Rodríguez Pacheco, Roberto Lorenzo (2022-04)
      Article
      Accés obert
      Case studies and numerical simulations show that the long-term stability of tailings dams largely depends on the evolution of their water content. Therefore, desiccation is one of the critical processes influencing the ...
