Abstract: The crystalline Freiberg gneiss is anisotropic in its hydraulic properties, shear and tensile failure, and wave velocity propagational behaviour. Its anisotropy depends not only on the magnitude of the principal stresses, but also on the foliation orientations relative to the principal stresses. In this study, the hydraulic and mechanical anisotropies are investigated in the laboratory under hydrostatic and triaxial stress conditions in order to aid the interpretation of the field hydraulic stimulation for in-situ stress measurements conducted in boreholes drilled in the underground research mine in Freiberg mine, Germany. The pore-pressure oscillatory hydraulic tests and velocity measurements were investigated under hydrostatic stress conditions representative of stresses......
