Properties of mine tailings for static liquefaction assessment

Static liquefaction has been associated with numerous recent failures of tailings storage facilities (TSFs) around the world (e.g., the 2019 Brumadinho failure). These failures lead to devastating consequences for the environment and civil infrastructure as well as the loss of human lives. In this study, we present trends for the mechanical …

This variation rule is closely related to the property of the tailings from Shuiyindong Gold Mine. Since the tailing particles are fine and the content of ultra-fine particles with the diameter below 20 μm is as high as 66.13%, the fineness is close to that of PC32.5 cement. Additionally, water is uniformly distributed on the surface of fine ...
