Comparison Between Deterministic and Probabilistic Stability Analysis, Featuring a Consequent Risk Assessment
Available to Purchase
Paper presented at the ISRM VII Brazilian Symposium on Rock Mechanics - SBMR 2016, October 19–22, 2016
Paper Number: ISRM-SBMR-2016-10
... SUMMARY: Slope stability analyses are largely carried out by deterministic methods and evaluated through a single safety factor. Although it is known that the geotechnical parameters can present great dispersal, such analyzes are considered fixed and known. The probabilistic methods, in turn...

Slope Stability Analysis of Open Pit Highwall Mining Excavations – A Parametric Study
Available to Purchase
Paper presented at the ISRM Conference on Rock Mechanics for Natural Resources and Infrastructure - SBMR 2014, September 9–13, 2014
Paper Number: ISRM-SBMR-2014-038
... excavations for 100m cover depth (slope height). The variation in safety factor of slopes for different slope angles at different cover depths can be seen in Figure 6. As expected, the safety factor decreases with the increase in the slope angle. Further, it can be seen in the Figure that the values of factor...

Geomechanical Studies for the Recovery of Pillars Through Experimental Mining in a Pilot Area in the Urucum Mine and Automated Monitoring
Available to PurchaseMauri Lopes Ferreira, Arildo Henrique de Oliveira, Wagner Castro, Alini Mancio, Frederico Tadeu Duarte, Rodrigo César Padula
Paper presented at the ISRM Conference on Rock Mechanics for Natural Resources and Infrastructure - SBMR 2014, September 9–13, 2014
Paper Number: ISRM-SBMR-2014-021
... utilized. During the work, geomechanical mapping of the galleries and pillars within the pilot area was performed so that experimental mining could be executed once the safety factors for the pillars (at their current dimensions) and the current excavation rate had been determined. The geomechanical...
