Automated dynamic control philosophy for sustainable energy savings on mine cooling systems
(North-West University (South Africa), 2019)Financial instability in the mining sector was identified as a significant reason for reduced production trends in South Africa. Coupled with increasing operational costs, the South African mining sector is confronted with ... -
An integrated energy efficiency strategy for deep mine ventilation and refrigeration
(IEEE, 2014)Mine-cooling and ventilation energy cost saving projects are implemented ad hoc and scattered throughout the system. Therefore, an overhead view and strategy is needed to help realise the total savings available on the ... -
Optimal utilization of a three-chamber pipe feeder system
(North-West University, 2018)South African gold production is decreasing year-on-year. This can be attributed to numerous challenges faced by the gold mining industry. One of these challenges is high operating costs of which electricity forms a large ... -
Optimising mining refrigeration systems through artificial intelligence
(North-West University (South Africa), 2021)The deep-level mining industry needs to overcome large operating costs to remain profitable. One of the largest contributors to operating costs is a mine’s refrigeration and ventilation system, which consumes up to 28% of ... -
Reducing energy consumption of mine cooling systems by controlling chilled water demand of mobile cooling units
(IEEE, 2014)Energy costs are increasing rapidly. Energy efficiency strategies are required to reduce electricity consumption for energy intensive operations. Cooling systems of deep level mines consume approximately 25% of their total ...
