Because rock composition, structure, mode of occurrence of different surface

Rock mechanics characteristics are the basis for geotechnical studies, because rock composition, structure, mode of occurrence of different surfaces, leading to differences in the mechanical properties of rock, for geotechnical engineering should be a combination of different environmental conditions and engineering requirements for rock physical characteristics, in order to determine the economic  polycrystalline diamond design and technical feasible engineering control measures to provide basic data. In this paper, Panzhihua Zhu mine Dongshan head deformation and failure of slope landslides example, through the structure of the surface shear slope rock mass, in situ shear, unloading and rheological rock mechanics test,abrasive wheels geological conditions, evaluated Dongshan head rock mechanical properties, recommended engineering control measures required to determine the physical and mechanical parameters and applied in practice, and achieved good results.
