... ABSTRACT: Geomechanical classifications have been used for the analysis of tunnels and mines since the 1970's. The database generated is huge: all types of lithologies, countries and works. However, there are few studies on its application to caves. The geotechnical stability of natural...

... characterization rqd bieniawski geomechanical classification Abstract Study of mechanical properties of rock masses is essential to the development of mining activities. Geomechanical classification systems are widely used to estimate rock properties. This paper presents a case study, which rock masses...

... geomechanical classification systems do not fully address the fundamentals required to predict the behaviour of weak rock masses. This paper presents an open pit mining application of a modified RMR (Bieniawski) classification system, as proposed by Cella et al. (2019), which attempts to differentiate materials...

The analysis of the support system was dictated by four geomechanical classifications (RSR, RMR...

... A retrospective analysis of some geomechanical classifications for rock masses is presented. It is shown that estimates of rock mass strength according to geomechanical classifications developed, e.g., for construction of tunnels and for ore mines can differ very much. Development...
