Analysing the influence of compressed air pressure on gold production
(North-West University (South Africa), 2020)Unreliable energy provision in South-Africa led to various high energy-consuming entities searching for new ways to optimise energy distribution. Due to the increasing need for energy saving initiatives on deep-level gold ... -
Applying a benchmark method to identify utility cost-saving opportunities on a platinum mine
(North-West University (South Africa)., 2022)South Africa’s energy and water demands are more significant than the supply thereof. This higher demand means Eskom cannot deliver enough power to South Africa. Furthermore, South Africa is a water-scarce country and water ... -
The cost-effectiveness of comprehensive system control on a mine compressed air network
(2014)Compressed air leakage accounts for up to 42% of electrical energy loss on a typical mine compressed air system. By using underground control valves it is possible to reduce the amount of air leakage. Underground valve ... -
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 ... -
Expanding compressed air management through cross cut isolation
(North-West University (South Africa)., 2022)Compressed air on deep-level mines is regarded as an important source of energy for underground mining operations, as the compressed air network forms the backbone of several mining processes over a 24-hour mining cycle. ... -
Future mine compressed air planning using digital twin simulations
(North-West University (South Africa)., 2023)Most deep-level gold mines use compressed air services for various applications that directly influence gold production. Amongst others, these applications include drilling, agitation and loading boxes. However, similar ... -
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 ... -
Improving efficiency of a mine compressed air system
(North-West University (South Africa) , Potchefstroom Campus, 2017)Eskom supplies electricity to South Africa, which experienced a capacity margin shortfall. Energy savings companies (ESCOs) implement demand side management (DSM) initiatives to reduce the power strain on the electricity ... -
Integrating various energy saving initiatives on compressed air systems of typical South African gold mines
(North-West University, 2011)Electrical energy is commonly used in households and in industry - demand continues to rise due to economic and population growth. This requires that energy suppliers must increase their supply capacity. The result is that ... -
Reducing energy consumption on RSA mines through optimised compressor control
(North-West University, 2010)South Africa experienced a severe shortfall in electricity supply during 2008. Eskom, the national electricity supplier, implemented several strategies to alleviate the situation. The Power Conservation Programme set the ...
