Geomechanic classification, Rock masses, Terrestrial laser scanningAbstract
Through three-dimensional digital image of a metacalcareous mine, obtained from a device called a terrestrial laser scanner, was conducted the respective rock mass classification. The object studied is the Saivá mine, located in Rio Branco do Sul, Paraná, Brazil. We evaluated, among other factors, the spacing between joints, the strength of intact rock and the orientation of the discontinuities in digital media. These results allow us to calculate Rock Quality Indexes, for example, using the methods of Priest and Hudson (1976, 1981) and Deere et al. (1967), which, together with other parameters, subsidized the rock mass classification of the Saivá mine by the methods of Bieniawski (1974), Barton et al. (1974) and Wickham et al. (1974). Results of classification show that the rock mass where Saiva mine is has a good geomechanical quality and it is possible to use the scanner in rock mass classification.
