Energy efficiency through variable speed drive control on a cascading mine cooling system
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 ...
Modernising underground compressed air DSM projects to reduce operating costs
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 ...
An integrated energy efficiency strategy for deep mine ventilation and refrigeration
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 ...
