      Comunicació de congrés
      Accés restringit per política de l'editorial
      The failure of the pond that stored the tailing of the mining activity of Aznalcóllar (1998) supposed one of the most catastrophic mine disasters ever worldwide. More than 400 scientific publications, including two special ...

    • El desastre de Aznalcóllar: ¿lodos o aguas ácidas? 

      Sanz Ramos, Marcos; Bladé i Castellet, Ernest; Dolz Ripollès, Josep; Sánchez Juny, Martí (2021-07)

      Accés obert
      La rotura de la balsa de estériles mineros del complejo de Aznalcóllar acaecida el 25 de abril de 1998 fue una catástrofe sin precedentes. Millones de metros cúbicos de un fluido complejo inundaron los cauces y riberas de ...

    • Failure mechanisms in brittle soils: a dam failure revisited with the material point method 

      Alonso Pérez de Agreda, Eduardo; Zabala, Francisco (2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The material Point Method (MPM) combines features of Finite Element and Discrete Particle methods. It is well suited to analyze geotechnical problems which involve large displacements and dynamic response. An explicit ...

    • Progressive failure of Aznalcóllar dam using the Material Point Method 

      Zabala García, Francisco; Alonso Pérez de Agreda, Eduardo (2011-01)
      Article
      Accés restringit per política de l'editorial
      The material point method, which combines features of finite-element and particle discretisation methods, has been extended to solve coupled flow-deformation problems in granular media. The method is applied to simulate ...

    • Reconstructing the Aznalcóllar mine accident 20 year later: numerical modelling of the flood 

      Sanz Ramos, Marcos; Bladé i Castellet, Ernest; Dolz Ripollès, Josep (CRC Press, 2020)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The Aznalcóllar mine-pond break is the most catastrophic mining accident regis-tered in the Iberian Peninsula (April 1998), and caused a tailings spill that affected around 45 km of the Agrio and Guadiamar Rivers. The flood ...

    • Revisiting the hydraulics of the Aznalcóllar mine disaster 

      Sanz Ramos, Marcos; Bladé i Castellet, Ernest; Dolz Ripollès, Josep; Sánchez Juny, Martí (2022-06)
      Article
      Accés obert
      The Aznalcóllar tailings pond failure (1998) is regarded as one of the severe ecological mine disasters ever reported. The spill of the mine tailings affected more than 60 km of the Agrio and Guadiamar rivers and caused ...

    • The failure of the Aznalcóllar tailings dam in SW Spain 

      Alonso Pérez de Agreda, Eduardo (2021-03)
      Article
      Accés obert
      The Aznalcóllar dyke failed and released much of its stored, saturated pyritic tailings after a process of progressive failure in the foundation clay. 1.5 Mm3 of tailings and 5.5 Mm3 of acidic water were rapidly discharged ...
