An interactive design tool for determination of Rock Mass Rating and Rock Mass Classification for mining and tunnelling conditions.
Notes on Rock Mass Rating (RMR)
- RMR values obtained are for mining and tunnelling applications
- Strength of Intact Rock is in terms of uniaxial compressive strength
- For assistance with interpretation of other conditions see RMR Design Tables
- For interpretation of Rock Mass Classification see RMR Design Tables
