Abstract
The paper presents the comparison of the most widely-applied rock-mass classifications RMR and Q and a system developed by VNIMI in Russia. It has been shown that the results obtained from using these systems for the forecast of rock mass stability and selection of support types enjoy a satisfactory conformity.
