ResumoRock mass classifications form the backbone of the empirical design approach which relates practical experience gained on previous projects to the conditions anticipated at a proposed site. They are widely employed in rock engineering. In fact, on many projects, the classification approach serves as the only systematic and practical basis for the design of complex excavations in rock. Most of the tunnels, mines, slopes and foundations constructed currently make use of a classification system. The best known classification system is the Terzaghi rock load classification, introduced over 45 years ago. Since then this classification has been modified [3] and new rock mass classification systems proposed. These systems took cognizance of the new advances in rock support technology, namely, rock bolts and shotcrete, as w.ell as addressing different engineering projects such as tunnels, chambers, mines, slopes, and foundations.
