Application of M&V 2.0 techniques to identify and quantify non-routine events
(North-West University (South Africa)., 2022)Energy efficiency measures (EEM) are implemented on mines to reduce energy consumption. The impact of an EEM must be determined to evaluate if any energy savings were achieved. This is done by applying measurement and ... -
Evaluating the feasibility of integrating mine compressed air systems for energy savings
(North-West University (South Africa), 2021)The South African metals and mining industry is under pressure to increase their production output. While South Africa’s production trend has been decreasing, even though it is the third largest gold reserve, the global ... -
Improved control of compressed air networks using machine learning
(North-West University (South Africa)., 2021)Mining companies in South Africa are under financial strain and so need to minimise expenses to stay profitable. Improving the efficiency of compressed air networks could lead to a significant reduction in electricity ... -
Increasing overall equipment effectiveness of drilling machines by means of data driven dashboards
(North-West University (South Africa), 2020)The decline in revenues, within the South-African mining sector, over the last decade is troublesome, considering a significant level of employment it creates. This study aims to create a link between improved operations ... -
Optimising mine cooling system performance through monitoring and analysis
(North-West University (South Africa), 2019)The South African mining industry is under ever-increasing economic pressure. The lack of shallow resources forces mining companies to increase workplace depths to exploit mineral resources. The increased depth of workplaces ... -
Reducing electrical costs for a mine ventilation system with the aid of simulation software
(North-West University (South Africa) , Potchefstroom Campus, 2017)Eskom, the South African state owned power utility, offers a demand side management (DSM) program that suggests different electrical energy tariffs during different times of the day for large consumers of electrical energy, ... -
Simulating operational improvements on mine compressed air systems
(North-West University (South Africa). Potchefstroom Campus, 2018)As the operational costs of deep-level mines increase and gold ore grades decrease, profitability in the South African gold mining sector is becoming a challenge. Electricity tariff increases moreover contribute to the ... -
Utilising automated control principles to reduce compressor operating costs on mines with limited infrastructure
(North-West University (South Africa)., 2023)The mining industry faces severe challenges with increasing operating costs at above-inflation rates, particularly the cost of electricity. Compressed air systems are extensively used on mines, making up roughly 20% of the ...
