Compressed air leakage accounts for up to 42% of electrical energy loss on a typical mine compressed air system. By using underground control valves it is possible to reduce the amount of air leakage. Underground valve ...

The energy provider in South Africa, Eskom, faces an increasing electricity demand. The need to ensure sufficient supply gave rise to Demand Side Management (DSM) projects scheme. The DSM focus has shifted to the mining ...

Eskom supplies electricity to South Africa, which experienced a capacity margin shortfall. Energy savings companies (ESCOs) implement demand side management (DSM) initiatives to reduce the power strain on the electricity ...

Unreliable energy provision in South-Africa led to various high energy-consuming entities searching for new ways to optimise energy distribution. Due to the increasing need for energy saving initiatives on deep-level gold ...

The South African metals and mining industry is under pressure to increase their production output. While South Africa’s production trend has been decreasing, even though it is the third largest gold reserve, the global ...

Mining companies in South Africa are under financial strain and so need to minimise expenses to stay profitable. Improving the efficiency of compressed air networks could lead to a significant reduction in electricity ...

South Africa’s energy and water demands are more significant than the supply thereof. This higher demand means Eskom cannot deliver enough power to South Africa. Furthermore, South Africa is a water-scarce country and water ...

Compressed air on deep-level mines is regarded as an important source of energy for underground mining operations, as the compressed air network forms the backbone of several mining processes over a 24-hour mining cycle. ...

South Africa experienced a severe shortfall in electricity supply during 2008. Eskom, the national electricity supplier, implemented several strategies to alleviate the situation. The Power Conservation Programme set the ...

As the operational costs of deep-level mines increase and gold ore grades decrease, profitability in the South African gold mining sector is becoming a challenge. Electricity tariff increases moreover contribute to the ...
