dc.description.abstractRock mass classification is in use throughout most of the mining industry, but not in common practice with narrow tabular gold-bearing orebodies at great depth. Many classification systems exist, but only one classification system was designed for mining applications, which is the MRMR system designed by Laubscher (1990). MRMR was mainly developed for caving applications, but through a thorough literature review and underground investigations, it was found to be the best suited for this particular application. The system has been modified to suit the narrow tabular reef mining environment at great depth, to assess the hanging wall objectively and to incorporate relevant mining adjustments, and rock mass rating properties. Therefore, although rock mass classification is not widely practised in the narrow tabular gold-bearing orebodies, this modified system is well suited for the environment. The system has been designed to be simple and easy to use.
