Engineering Application of Rock Mass Classifications Systems
Rock mass classification is widely used throughout the underground mining industry in both coal and hard rock mines. Civil engineering project like mines, dam, can be constructed properly with sound and in depth knowledge of existing nature in advance. The classification systems used today should, strictly speaking, either be described as rockmass characterization systems or empirical design methods, as long as the outcome is not organized into classes. Rockmass classification is widely used throughout the underground mining industry in both coal and hard rock mines. Rock mass classification system uses rock mass modulus for characterization of systems: RMR, Q, GSI and others. These are based on empirical relations between rockmass parameters and engineering properties widely used as a tool in determining the stability of structure such as tunnels, slopes, foundations. In this study, uniaxial compressive strength, modulus ratio and direct shear tests has been performed in order to classify the double jointed rockmass, artificially made of POP and POP lime mix. This classification can thereafter give a probable direction of Rock engineering design concept.
