Geomechanical classification
WebOct 1, 2024 · Currently, two of the most widely used classification systems are the RMR (Rock Mass Rating), created by Bieniawski (1976) and later revised ( Bieniawski, 1989 ), and the GSI (Geological Strength Index), conceived by Hoek et al. (1994). WebGeomechanical classifications are a procedure for characterizing rock masses from field and borehole data, and are applied mainly to tunnels, because of the difficulty of studying …

WebIn the last decade, in the mining district of Zaruma-Portovelo, there has been significant land subsidence related to uncontrolled mining activity. The purpose of this work was to carry out a surface and underground geomechanical characterization of a mining sector north of the city of Zaruma that allows the definition of potentially unstable areas susceptible to the …
The rock mass rating (RMR) is a geomechanical classification system for rocks, developed by Z. T. Bieniawski between 1972 and 1973. Since then it has undergone multiple modifications out of which, RMR89 is commonly used. Recently RMR14 has been proposed to improve the RMR performance by … See more The following six parameters are used to classify a rock mass using the RMR system 1.
