It consists of a cylindrical probe which is inserted into the ground in a borehole, by self-boring or by pushing, and is expanded against the soil or rock to obtain a pressure-expansion curve. Interpretation methods based on cavity expansion theory applied to realistic model...
View ArticleLarge-scale mining operations generate vast quantities of tailings that are deposited in hydraulic-fill tailing dams in the form of slurries. Stability of these impoundments require investigation of water table configuration, aquifer boundaries, site characterization and determination of short and long term properties of tailings. These aspects are eval...
