Paper presented at the ISRM International Symposium - EUROCK 2020, June 14–19, 2020
Paper Number: ISRM-EUROCK-2020-057
... Abstract Photogrammetry and optical televiewer are used to investigate discontinuities occurring in the highwall of the bench and in eleven blastholes in two blasts. The measuring conditions involve lower resolution for photogrammetry models. Discontinuity mapping was done manually by the same...

Paper Number: ISRM-EUROCK-2020-056
... Abstract The knowledge of geometrical properties of discontinuities is of crucial importance in the rock mass characterisation process. Recent advances in photogrammetry allow for an easy digitisation procedure of rock surfaces so that digital 3D models can be used for remote site...

Paper presented at the ISRM European Rock Mechanics Symposium - EUROCK 2017, June 20–22, 2017
Paper Number: ISRM-EUROCK-2017-106
... Abstract Discontinuities play a key role in the mechanical, hydraulic and deformational behaviour of rock masses, frequently having a considerable influence on the stability of rock slopes. They can be characterized by several geometric parameters as the orientation, persistence, spacing, etc...

... conditions. In any such scenario, increased heat exchange with an exposed rock mass surface will cause thawing to occur. In general, a rock mass is stronger in frozen conditions than in dry conditions (i.e. without ice or water), but a rock mass will be least strong at the time ice-filled discontinuities are...
