Integrating various energy saving initiatives on compressed air systems of typical South African gold mines
(North-West University, 2011)
Electrical energy is commonly used in households and in industry - demand continues to rise due to economic and population growth. This requires that energy suppliers must increase their supply capacity. The result is that ...
Sustaining compressed air DSM project savings using an air leakage management system
(North-West University, 2010)
Unreliable and unsustainable electricity supply has been experienced in South Africa since
2007. Eskom implemented Demand Side Management (DSM) as a short-term solution to
alleviate this problem. Several compressed-air ...
The cost-effectiveness of comprehensive system control on a mine compressed air network
(2014)
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 ...
Sustained energy performance on compressed air systems for expanding gold mines
(2013)
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 ...
Improving efficiency of a mine compressed air system
(North-West University (South Africa) , Potchefstroom Campus, 2017)
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 ...
Reducing energy consumption on RSA mines through optimised compressor control
(North-West University, 2010)
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 ...
Simulating operational improvements on mine compressed air systems
(North-West University (South Africa). Potchefstroom Campus, 2018)
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 ...
