The adjustment factors depend on future (susceptibility to) weathering, stress environment, orientation, The combination of values of RMR and MRMR determines the so-called reinforcement potential.
A rock mass with a high RMR before the adjustment factors are applied has a high reinforcement potential, and can be reinforced by, for example, rock bolts, whatever the MRMR value might be after excavation.
The parameter is dependent on a maximum of three discontinuity sets that determine the size and the form of the rock blocks.
The condition parameter is determined by the discontinuity set with the most adverse influence on the stability.
The concept of adjustment factors for the rock mass before and after excavation is very attractive.
