According to Hoek-Brown failure criterion and equivalent-area principle
strength parameters of engineering rock masses can be estimated by data from lab test and field geological survey. These parameters are naturally applied to engineering classification of rock masses. In terms of deep-buried engineering
this classification practically reflects local environment and mechanical states of rock even better than traditional BQ classification.
