Benefits of improved performance monitoring of mine cooling systems
(IEEE, 2014)Mine cooling system components are an integral part of a mine's ventilation system. A mine's reliance on these capital intensive components are set to increase as mines deepen. Mine cooling systems consume up to a quarter ... -
Energy efficiency through variable speed drive control on a cascading mine cooling system
(IEEE, 2014)An ever-expanding global industry focuses on energy supply and use. Cost-effective electrical energy production and reduced consumption pave the way for this expansion. Eskom's demand-side management (DSM) initiative ... -
The impact of reducing mine chilled water supply during periods of low production
(IEEE, 2014)As part of the Demand Side Management (DSM) initiative, Eskom partially funds load management and energy efficiency projects. Large industries are therefore willing participants in the Eskom funded electricity savings ... -
Implementing DSM interventions on water reticulation systems of marginal deep level mines
(IEEE, 2014)South Africa's steep electricity tariff increases have forced the mining industry to be more cost effective. One way is by implementing demand side management (DSM) projects. Energy saving priorities focused mainly on mines ... -
An integrated energy efficiency strategy for deep mine ventilation and refrigeration
(IEEE, 2014)Mine-cooling and ventilation energy cost saving projects are implemented ad hoc and scattered throughout the system. Therefore, an overhead view and strategy is needed to help realise the total savings available on the ... -
An integrated methodology to measure and verify energy conservation under incentive-based irrigation pumping programmes
(North-West University (South Africa), 2019)Water scarcity and droughts have become a looming threat in many counties worldwide. In South Africa, a water crisis is upon the country and estimations show a supply shortfall of 17% by 2030. When considering water ... -
Modernising underground compressed air DSM projects to reduce operating costs
(IEEE, 2014)Compressed air is an energy intensive utility that is frequently used in the deep level mining industry. Most compressed air networks are designed to ensure ample compressed air supply to consumers. This has created the ... -
Optimising mining refrigeration systems through artificial intelligence
(North-West University (South Africa), 2021)The deep-level mining industry needs to overcome large operating costs to remain profitable. One of the largest contributors to operating costs is a mine’s refrigeration and ventilation system, which consumes up to 28% of ... -
Practical considerations in energy efficient compressor set-point control strategies
(IEEE, 2014)Compressed air supply and demand strategies have received significant attention since integrated demand management was initiated by Eskom. Due to the expensive nature of this vastly utilised energy carrier, every increase ... -
Strategies for energy efficiency funding in the absence of industrial Eskom-IDM support
(IEEE, 2014)In the absence of industrial Eskom-IDM (Industrial Demand Management) funding, industry is forced to look elsewhere for energy efficiency project funding. This paper outlines various taxes and government incentives for ...
