A generic method for rock mass classification
Journal of Rock Mechanics and Geotechnical Engineering, 2018 Rock mass classification (RMC) is of critical importance in support design and applications to mining, tunneling and other underground excavations. Although a number of techniques are available, there exists an uncertainty in application to complex ...
