Abstract:
In this work the characterization of phyllites in the Córrego do Sítio Mine, Santa Bárbara, MG, is discussed, as well as some factors that influence the shear strength along the foliation surface. Results of mineralogic description, physical indices and direct shear tests of three areas in this mine are presented. Weathering acts on the variability of some properties, such as the porosity, void ratio, dry specific gravity, and also on the shear strength, with considerable reduction of the cohesion after alterability tests. In addition, the roughness observed on the foliation surface in the rocks of Crista pit influences the rock mass behaviour, increasing its shear strength.
