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 ...
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 ...
Integration of electricity cost saving interventions on a water distribution utility
(2014)
Electrical energy has become a very important and integrated part of the current era. Electricity cost saving interventions, such as load shifting, form part of demand side management (DSM) interventions. DSM interventions ...
Development of an energy management solution for mine compressor systems
(North-West University, 2010)
Eskom is under increasing pressure to provide reliable and sustainable electricity. Demand Side Management (DSM), offers a short– to medium–term solution to this problem. During 2009, the mining sector consumed approximately ...
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 ...
An automated solution to facilitate sustainable DSM in the mining environment
(North-West University, 2008)
South Africa is experiencing a serious electricity supply problem. This problem is expected to persist until at least 2012. During the winter of 2006 load shedding and electricity supply-cuts started occurring in the Western ...
Electricity cost optimisation of a surface potable water pump system
(North-West University, 2007)
South Africa is fast approaching an era where its electrical energy demand will surpass the generating capacity of it's primary utility. The reason for this is due to the fact that over the past 10 years, the economic ...
Load shift through optimal control of complex underground rock winders
(North-West University, 2009)
South Africa's national power utility, Eskom, initiated a Demand Side Management
(DSM) drive to help alleviate the electricity supply shortage experienced in South
Africa. The focus of this study is on a load-shifting ...
Improved control of clear water underground pumping system for demand side management at an interconnected South African goldmine
(North-West University (South Africa) , Potchefstroom Campus, 2016)
Deep level clear water pumping at gold mines accounts for nearly 30 % of a mine’s total electricity consumption. Demand side management (DSM) initiatives for various deep level water pumping systems have been implemented ...
Optimising gold ore transportation systems for electricity cost savings
(North-West University (South Africa) , Potchefstroom Campus, 2015)
Electricity is an essential but limited resource in South Africa. Limited supply capacity and
growing demand cause electricity prices to increase rapidly, therefore, reducing electricity
consumption. Costs are critical ...
