A Proposal to Standardize Vulnerability Analyses of Flow Liquefaction of Tailings Dams

Alejo Sfriso, Mauro Giuliano Sottile, Ariel Terlisky , Felipe López Rivarola, Arcesio Lizcano, Osvaldo Ledesma - November 14, 2024

Following the implementation of the GISTM guideline (ICMM 2020) the team at SRK has produced assessments of the vulnerability of tailings dams to flow liquefaction using numerical methods in mines around the world. This paper outlines a proposed procedure based on our experience.
