Assessment of the national DSM potential in mine underground services
(North-West University, 2003)ESKOM is moving towards a price structure for electricity which reflects, as far as possible, the real cost of generation. It is called real time pricing (RTP). ESKOM developed this cost structure to coax customers to ... -
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 ... -
Effect of product bed height and air velocity on the drying rate of extruded maize pellets
(North-West University (South Africa) , Potchefstroom Campus, 2015)In the food processing industry, specifically food drying and cooling, there is still a lack of available information that is based on experiments and reliable data. A specific product that has not been investigated is ... -
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 ... -
High pressure water supply strategy for mine bulk air coolers
(North-West University (South Africa)., 2022)South African gold mines face many challenges with rising production costs being amongst the biggest concerns. Labour unrest and low economic growth along with increased production costs are affecting the productivity and ... -
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 ... -
Influence of cold-water immersion on limb blood flow after resistance exercise
(Taylor & Francis, 2017)This study determined the influence of cold (8°C) and cool (22°C) water immersion on lower limb and cutaneous blood flow following resistance exercise. Twelve males completed 4 sets of 10-repetition maximum squat exercise ... -
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 ... -
A method for transient simulation of integrated ventilation and cooling systems in deep-level mines
(North-West University (South Africa)., 2022)Mine ventilation and cooling systems ensure adequate air temperature and flow in underground working areas. These are large and complicated systems that are integrated and interdependent. As underground mines expand to ...
