Two Rivers Platinum Mine: the orebody, the mining method; a perfect match
Witryna4 paź 2024 · Geometric orebody configuration is related to the shape, size and continuity of a deposit while grade distribution defines the potential value of the deposit. Deposits such as seams, veins, lenses, lodes and stratiform orebodies usually require selective mining in order to minimize dilution, especially if the orebodies are not very … Witryna4 sie 2016 · Vertical development is frequently high (depending on the orebody configuration) with typically five to ten benches exploited per year in an individual pushback. This often results in short pit wall permanence and a strong interaction between pushbacks. Ore exposure and the balance of the mine plan are critical, with … philips avent sealing disc

Witryna16 kwi 2010 · "While the method is simple, the best solution is different for every orebody so CSIRO has developed computational methods to optimise the solution for different orebody configurations," Dr ... Witryna2 mar 2024 · The stress evolution and failure characteristics of overburden were studied during multi-stope mining for a gently inclined thin orebody. Firstly, an indoor physical experiment was conducted on the excavation of a multi-stope mine with an orebody dip angle of 20°. The results show that the vertical stress concentration area gradually … trustsheep
