Rock Mass Rating spatial estimation by geostatistical analysis [PDF]
International Journal of Rock Mechanics and Mining Sciences, 2014 Abstract This work aims to estimate the Rock Mass Rating of 200 km 2 area of the Italian Central Alps, along San Giacomo Valley (province of Sondrio). The regional geological setting is related to the Pennidic Nappe arrangement, which is characterized by the emplacement of sub-horizontal gneissic bodies, separated by meta-sedimentary cover units ...

Characterization of rock slopes through slope mass rating using 3D point clouds [PDF]
International Journal of Rock Mechanics and Minings Sciences, 2016 Rock mass classification systems are widely used tools for assessing the stability of rock slopes. Their calculation requires the prior quantification of several parameters during conventional fieldwork campaigns, such as the orientation of the ...

International Journal of Mining Science and Technology, 2020 The rock mass rating (RMR) has been used across the geotechnical industry for half a century. In contrast, the coal mine roof rating (CMRR) was specifically introduced to underground coal mines two decades ago to link geological characterization with ...

Updating of the Hierarchical Rock Mass Rating (HRMR) system and a new subsystem developed for weathered granite formations [PDF]
International Journal of Mining Science and Technology, 2014 The RMR system is still very much applied in rock mechanics engineering context. It is based on the evaluation of six weights to obtain a final rating.

Powder factor prediction in blasting operation using rock geo-mechanical properties and geometric parameters [PDF]
International Journal of Mining and Geo-Engineering, 2022 Prediction of powder factor is a major activity while preparing drilling and blasting operation, as the total production cost depends on it. It is a major input parameter in blast design as it influences the efficiency of subsequent operations in mining.
