Implementing energy efficiency measures on the compressed air network of old South African mines
(North-West University, 2011)
anthracite with the highest fixed carbon and lowest ash contents exhibited the smallest shrinkage during in situ TMA calcination. High fixed carbon, low ash type anthracites are therefore less prone to dimensional instabilities ...
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 ...
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 ...
Verification procedures to ensure consistent energy measurements
(2014)
The majority of energy conservation measures (ECM) implemented by South African Energy Service Companies (ESCOs), are funded by the Eskom Demand Side Management (DSM) initiative. In 2013 Eskom reported a total DSM savings ...
Power system design guidelines to enhance the reliability of cellular networks in Africa
(2014)
Cellular networks in Africa have grown exponentially over the past 10 years and their data centres (DCs) on average consume 3 MW of electrical power. They require a reliable electrical power supply and can have a downtime ...
Automated control of mine dewatering pumps
(2014)
Deep gold mines use a vast amount of water for various purposes. After use, the water is pumped back to the surface. This process is energy intensive. The control is traditionally done with manual interventions. The purpose ...
Maintenance procedures on DSM pumping projects to improve sustainability
(2015)
Effective dewatering and refrigeration are crucial in mining. Cascading dewatering systems, which are common in deep gold mines, are very energy intensive. These systems present several opportunities for energy cost savings ...
Challenges faced during implementation of a compressed air energy savings project on a gold mine
(2014)
Demand side management (DSM) initiatives have been introduced by Eskom to reduce the deficit between the electricity generation capacity and the electricity usage within the country. DSM projects enable Eskom to reduce ...
Analysing the effect of DSM projects at South African cement factories
(2015)
In any developing country an increasingly higher demand for electricity supply exists. South Africa experienced load shedding during late 2007 and early 2008 and again in 2014 due to a supply shortfall. New power stations ...
Mitigating construction risk in the design and planning of high-voltage transmission lines
(North-West University (South Africa) , Potchefstroom Campus, 2015)
The Eskom transmission network in South Africa is rapidly expanding with the addition of new power stations such as Medupi, Kusile and multiple independent power producers. The changing grid code requirements to ensure ...
