Rock Mass Classification
Ground classification; Rock strength classification
A classification system that captures all relevant information on the composition and characteristics of a rock mass to provide initial estimates of support requirements and to provide estimates of the strength and deformation properties of the rock mass.
One of the earliest classification systems for rock was developed by Terzaghi (1946). The classification system was developed as a method of classifying rock masses and evaluating rock loads based on qualitative assessments.
