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 South African mining industry purchased 13.8% of the electricity supplied by Eskom in 2015. Deep-level mines are some of the largest electricity consumers in the mineral extraction industry. The electricity costs of ...

Large cooling systems consume up to 25% of the total electricity used on deep level mines. These systems are integrated with the water reticulation system to provide chilled service water and cool ventilation air. Improving ...

Approximately 75% of small, medium and micro enterprises (SMMEs) created in South Africa (SA) fail in the first year. This is a serious socio-economic problem as SMMEs in South Africa employ over 60% of the workforce and ...

Because of a continuous increase in the demand for electricity in South Africa the country’s largest electricity utility (Eskom) has been under strain to provide electricity. An expansion programme to generate more electricity ...

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 ...

This study describes the development and use of a mathematical model that will enable mine operators to minimise the costs of electricity consumed by the ventilation and refrigeration systems used for environmental control ...

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 ...

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 ...

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 ...
