Thursday, 27 June 2019: Technical Visit


Technical Visit - Mponeng Gold Mine

AngloGold Ashanti’s Mponeng gold mine, located south-west of Johannesburg in South Africa, is currently the deepest mine in the world. The operating depth at Mponeng mine ranged from between 2.4km to more than 3.9km below the surface by the end of 2012. Ongoing expansions have resulted in deeper digging at Mponeng, pushing the record to beyond the four kilometre mark.

Thursday, 27 June 2019: Site Visit


Site Visit - University of Pretoria Geotechnical centrifuge facility

Physical model studies are a versatile means to investigate a wide range of engineering problems. A geotechnical centrifuge is used to accelerate small-scale models to high accelerations to impose a stress distribution within the model corresponding to that occurring in the full-scale situation. For example, a model with a scale of 1:50 needs to be accelerated to 50 times the earth’s gravity to impose the same stresses in the model as in the field. This is necessary in instances where realistic material behaviour depends on the correct stress distribution. Typical applications include geotechnical and mining related problems.
