Rock mass classification

Rock mass classification is an extremely powerful and useful tool in rock engineering, and this lecture gives an introduction to rock mass classification. It puts a number to the quality of a rock mass, and numbers facilitate the application of engineering in rock masses. Several rock mass classification systems are described in the lecture, as well as examples of applications of classification in the evaluation of stability of excavations, estimation of rock support requirements, and determination of rock mass deformation and strength parameters. The lecture will help new users to become proficient in the application of rock mass classifications.
