Analysing the impact of refurbishing precooling towers on a deep-level mine
(North-West University (South Africa), 2020)The challenges faced by South African gold mines are increasing operating costs, resulting in a decreased profit margin. Increased mining depths are one of the highlighted challenges but is required to remain competitive ... -
Benchmarking electricity use of deep-level mines
(North-West University (South Africa) , Potchefstroom Campus, 2016)Electricity consumption, and the cost thereof, has become a large contributor to operating costs in deep-level mining in South Africa. Up to 60% of electricity used on deep-level mines can be attributed to five high power ... -
A generic software platform for performance monitoring of deep-level mine systems
(North-West University (South Africa), 2020)Systems of a deep-level mining operation are integral to the working of a mine. These systems help with water reticulation, compressed air, and energy used for mining minerals. A mine relies on these capital-intensive ... -
An integrated simulation-based method for deep-level mine dewatering planning
(North-West University (South Africa)., 2022)The South African gold mining industry has declined rapidly over the last decades. The main contributors are rising operational costs and fluctuating gold prices. Due to increased electricity costs and increased mining ... -
A method for transient simulation of integrated ventilation and cooling systems in deep-level mines
(North-West University (South Africa)., 2022)Mine ventilation and cooling systems ensure adequate air temperature and flow in underground working areas. These are large and complicated systems that are integrated and interdependent. As underground mines expand to ... -
Prediction model for the performance of a methane-fuelled spark-ignition engine at a deeplevel mine
(North-West University (South Africa)., 2022)Electrical energy supply in South Africa is unreliable and the cost of electricity has been increasing significantly annually. This negatively impacts high energy consumers, especially deep-level mines. Therefore, reducing ... -
A simulation-based horizontal water transport management strategy in deep-level mines
(North-West University (South Africa)., 2023)Dewatering and water transfer pumping are two of the main consumers of electricity in the South African mining industry. In the ever-unstable electricity supply regime, it is important to consider all possible angles to a ...
