CPUT Wins Greener Mining Design Challenge
The panel of engineering specialists who gathered together to review entries for the PneuDrive Challenge 2013 Engineering Design Competition, concluded that an elegant design from two students from the Cape Peninsula University of Technology was the best entry.
1st Place – Cape Peninsula University of Technology – Waste Granite to Cobblestone Machine
After two intensive days of judging the panel concluded and agreed that this entry presented the best technical solution for solving a real-life business and environmental problem. Students Christian Mpiana and Gareth Hardman submitted a design that proposes the rehabilitation of abandoned granite mines by turning surplus “waste” granite blocks into usable cobblestones. These can then in turn be used to develop access roads and walkways in rural areas. Apart from the direct benefit paved roads and paths will bring to these areas, they proposed that other possible business interventions around the system could generate job creation. Lecturer Francois Hoffman expressed that his students winning the competition was the highlight of his year.

2nd Place – Tshwane University of Technology – The Dust Buster
The difference between first and second place was a mere 3 percentage points – the closest margin in the history of the competition. However, students Alexander Jansen van Vuuren, Francois van Dyk, Myron van Staden and Daniel Posthumus, can be proud of the fact that their design won the Innovation Prize. They submitted a unique design concept that combines the use of low frequency sound waves, extraction fans and wireless systems, to address the problem of removing dust in a mining environment.
3rd Place – WITS University – Tailings Dam Water Solar Still
Students Gregory Behrens, Travis Bennett, Paul Hon, and Thomas Wyszkowski-Korwin submitted an equally unique design concept that focussed specifically on addressing water losses in tailings dams.
