Paper presented at the ISRM AfriRock - Rock Mechanics for Africa, October 3–5, 2017
Paper Number: ISRM-AFRIROCK-2017-073
... failure mechanism. Analysis of low rock mass quality zones combined with the jointing orientation may provide an improvement in the assessment of instabilities. The aim of this paper is to develop a rock mass model of an open pit mine under active operation, based on extensive field mapping. Through...

... available at that time. With additional geotechnical data available from field mapping, core drilling, and laboratory testing, efforts were made to evaluate the stability of the crown pillar. Empirical and analytical methods were applied to determine the factor of safety for the crown pillars of various...

... Columbia, Canada. We present the mapping of rock discontinuities for numerical modelling using a hierarchical geological structure order. Large-scale geological structures which were identified and mapped on the pre-failure and present-day topography are used in a preliminary analysis of the rock slope...

... future failure occurrence. The investigation involved a detailed area inspection, geological mapping, rock mass characterisation, discontinuity survey, kinematic analysis and a back-analysis. The field inspection revealed that the shear zone is composed of sheared and friable kimberlite, calcite, pyrite...
