Paper presented at the ISRM VIII Brazilian Symposium on Rock Mechanics - SBMR 2018, August 28–September 1, 2018
Paper Number: ISRM-SBMR-2018-01
... structural characteristics of the discontinuities, slope height and indications of activity. The reduction of the slope height with the construction of benches and the cleaning of the mining faces are possible mitigation measures to prevent rock blocks from falling. Benches with about 7 to 8 m of height and...

... multiplication of the uniaxial compressive strength of intact rock by a reduction factor of strength, named JP, which represents the effects of discontinuities on the strength of rock masses. JP factor is a combination of the block size, measured in terms of volume (Vb), and the joint condition factor of the...

Paper Number: ISRM-SBMR-2016-05
... SUMMARY: Roughness characterization and JRC estimation have been made on rock joints of the Monte Seco tunnel. The authors have adapted field profiling of discontinuity surfaces to be able to estimate JRC using 3D laser scanner images. Results indicate similarity between traditional and laser...
