In operational open pit mines, large rock surfaces are exposed daily and hundreds or thousands of new discontinuities are exposed, all of which may results in the formation of unstable keyblocks and wedges. It is impractical to attempt to map each discontinuity and carry out a stability analysis Read more... about Bench Berm Design Using Probabilistic Keyblock Analysis

Kinross Gold Corporation has several porphyry/epithermal gold properties in Maricunga gold belt in northern Chile. The Maricunga site comprises the operating Verde pit and the Pancho deposit, currently under development. Currently active operations are all open pits mines of a medium scale, and Read more... about Slope Design for Maricunga Mine in Chile

Significant developments in numerical modelling have been achieved during the last decade, but validation of these techniques is required to build up confidence. As these developments represent a significative advance for mining geomechanics, this paper focuses on the application of the Read more... about Estimation of Rock Mass Strength Using the Synthetic Rock Mass (SRM) Approach and Particle Flow Modelling

The Cuajone porphyry copper deposit is located on the western slopes of Cordillera Occidental, the southern Andes of Peru. The current pit measures about 2.5 km east–west, 3.0 km north–south, and at the end of 2012, had a maximum depth of 950 m. Mining by open pit methods commenced in 1976 and Read more... about Slope Design at Cuajone Pit, Peru

Water content in rock units present in open pit mines has significant effects on pore pressure and in slope stability. For this reason, pore pressure distribution throughout the pit represents one of the most important factors in slope stability analysis, obtainable through groundwater numerical Read more... about Modelling Fractured Rock Heterogeneity in an Open Pit: Groundwater Model Calibration using Pilot Points

Porphyry copper deposits are characterized by a rock mass with a stockwork of mineralized veins and veinlets affecting the strength behavior of the intact rock and rock mass. The observation of tested samples and blocks at draw points pointed out that veinlets and veins have a high participation Read more... about A methodology to select valid results from Lab tests to estimate properties of intact rock with microdefects
