Converting an ice storage facility to a chilled water system for energy efficiency on a deep level gold mine
(2015)The South African gold mining sector consumes 47% of the mining industry’s electricity. On a deep level gold mine, 20% of the energy is consumed by the refrigeration system. The refrigeration system cools 67 ˚C virgin rock ... -
Cost and energy savings on mine surface cooling systems
(North-West University (South Africa) , Potchefstroom Campus, 2017)The South African national power utility, Eskom, is struggling to meet the high electrical energy demand. The problem is due to the shortage of generating capacities as a result of delays in the building of new power ... -
Developing a dynamic control system for mine compressed air networks
(2014)Mines in general, make use of compressed air systems for daily operational activities. Compressed air on mines is traditionally distributed in two typical fashions. Firstly, direct pipe feed systems for single shafts or ... -
Developing a framework for managing compressed air in the Platinum Group Metal Mining Industry in South Africa
(North-West University (South Africa), 2020)South Africa is home to the Bushveld Igneous Complex, the largest known platinum group metal (PGM) resource in the world, which makes South Africa the top global PGM-producing country. Unfortunately, the sustainability of ... -
Developing ESCO procedures for large telecommunication facilities using novel simulation techniques
(North-West University, 2006)Peak electricity demand in South Africa will exceed the available operational generation capacity in 2007. The state utility Eskom is addressing this challenge, inter aha, with the implementation of the Demand-side ... -
The development and implementation of an energy management information system for industries
(North-West University (South Africa), 2020)There is a global drive to reduce energy consumption and improve energy efficiency. These drivers include the taxation of carbon emissions and the increase in energy costs. Companies therefore need to improve their operational ... -
The development of a system to optimise production costs around complex electricity tariffs
(North-West University, 2012)Rising South African electricity prices and reduced sales following the 2008 economic recession have led cement manufacturers to seek ways to reduce production costs. Prior research has shown that reduced electricity costs ... -
Development of an energy management solution for mine compressor systems
(North-West University, 2010)Eskom is under increasing pressure to provide reliable and sustainable electricity. Demand Side Management (DSM), offers a short– to medium–term solution to this problem. During 2009, the mining sector consumed approximately ... -
A dynamic optimal control system for complex compressed air networks
(North-West University (South Africa) , Potchefstroom Campus, 2016)Mines use large compressed air networks to supply shafts and processing plants with compressed air. These networks can be complex where multiple compressors are located at different locations. To add to the complexity of ... -
Energy management by means of fault conditions on active magnetic bearing systems
(IRET (Institute of Research in Engineering and Technology), 2013)This paper presents the use of fault conditions on active magnetic bearing (AMB) systems as an energy management tool to improve the operation of AMB systems. Fault conditions on AMB system are broadly classified ...
