Novel solutions for compressed air demand management on deep-level mines
(North-West University (South Africa), 2020)
Mining makes a significant contribution to South Africa’s economy (7.3% of the gross domestic product) and provides direct employment to more than 450 000 people. The bulk of South Africa’s mineral wealth lies in deep-level ...
Evaluating different statistical regression models for industrial energy measurement and verification
(North-West University (South Africa), 2020)
The worldwide concern regarding the environmental impact of using fossil fuels as an energy source leads to the increased interest in improving energy efficiency. The energy efficiency of existing facilities can be improved ...
Ensuring long-term energy savings in South African mines by improving energy data
(North-West University (South Africa), 2021)
South African mines experience higher-than-inflation electricity tariff increases, additional expenses such as carbon taxes and mounting environmental obligations. The mining sector is, therefore, forced to maintain long-term ...
Using simulation to prioritise implementation of platinum mine compressed air efficiency solutions
(North-West University (South Africa), 2021)
Platinum mines are facing several challenges and a higher-than-inflation increase in electricity costs is amongst the most significant. Compressed air accounts for up to 38% of a platinum mine’s energy consumption. To ...
Sustainable use of inlet guide vanes to reduce energy consumption of main ventilation fans
(2021)
The rising cost of electricity has urged mines to research and implement new energy-saving
initiatives. Little research has focused on energy saving techniques on main ventilation fans
(MVFs). MVFs extract hot, humid air ...
