Northam Platinum Limited Mining Africa
The Booysendal mine was opened in 2013 and consists of three mines that produce around 160,000 oz of refined Platinum Group Metals per annum. In 2015, Northam Platinum acquired Everest Platinum mine from Aquarius Platinum. The company also acquired a 7.5% share in Pandora mine alongside Lonmin and Anglo American Platinum.mine, whereas a less conservative design may lead to a mine-wide collapse. The collapse at the Everest platinum mine, where an alteration zone was present, was studied in detail by Couto and Malan (2023).

A Limit Equilibrium Model to Simulate the Large-Scale
at the Everest Platinum Mine P. M. Couto1 D. F. Malan1 Received: 20 May 2022 / Accepted: 20 September 2022 / Published online: 5 October 2022 Two areas of the mine were simulated, namely part of the collapsed area and a second area, with larger pillars that is still stable. This allowed for a preliminary calibration of the limitThis study investigated the use of a limit equilibrium model to simulate the time-dependent scaling of hard rock pillars. In the manganese bord and pillar mines in South Africa, extensive scaling is observed for pillars characterised by a high joint density. It appears that the scaling occurs in a time-dependent fashion. Evidence for this is the A Limit Equilibrium Model to Simulate Time-Dependent

Th e Everest Platinum Mine is located between Lydenburg and Dullstroom in some of the most picturesque and steep landscapes in the country. Th e Groot Dwars River, near which the box-cuts are located, is in a valley approximately 850 m below the adjacent mountains. Figure 1 Proposed developments at the Everest Platinum MineSynopsis This paper describes the evaluation of a limit equilibrium model to simulate the behaviour of crush pillars in platinum mines. An analytical model was derived to calculate the residual average pillar stress (APS) values of the crush pillars. The values predicted by this model were compared to the numerical values obtained from TEXAN simulations. In [PDF] Evaluation of a limit equilibrium model to simulate
