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 ...
Improving electricity forecasting processes on platinum mines
(North-West University (South Africa)., 2022)
Electricity is a fundamental resource used in mining, and as a result, is a large contributor to mine working cost. It is therefore important for mines to accurately budget their electricity expenditure in order to make ...
Evaluating localised ventilation improvements on deep-level mines using simulation models
(North-West University (South Africa), 2020)
The ventilation system of a mine is responsible for providing sufficient airflow in terms of quantity and quality. To ensure a safe and healthy environment, the main fans dilute and exhaust poisonous gases and dust throughout ...
Reconfiguring deep-level mine dewatering systems for increased water volumes
(North-West University (South Africa), 2020)
Deep-level mines are faced with a host of challenges that can pose a threat to the safety of underground mine employees. Significant among these threats is the risk of underground floods as a result of fissure water flowing ...
Validating the integrity of single source condition monitoring data
(North-West University (South Africa), 2020)
Vast amounts of data are generated daily and play an important role in decision-making and performance evaluation. Ill-informed decisions can have costly, negative effects. For this reason, confidence in the data used is ...
Development of an integrated project sustainability model using digital mining solutions
(North-West University (South Africa), 2020)
Deep-level gold mining in South Africa faces various economic and social challenges. It is thus crucial to implement successful and sustainable projects. Project management models and digital solutions have shown to increase ...
Novel approach for improved control processes on ageing mine refrigeration systems
(North-West University (South Africa), 2020)
Worker safety remains one of the top priorities in South African deep-level gold mines. Due to their operating depths, these mines are heavily dependent on artificial cooling. Large refrigeration systems are commonplace ...
Practical approach to analyse mine pneumatic drilling performance
(North-West University (South Africa), 2020)
South African deep-level mines were challenged over the last couple of years as production trends declined and the commodity price for PGM’s and gold decreased from 2016. The labour costs and operational costs are also ...
Determining the integrity of single-source condition-based maintenance data
(North-West University (South Africa)., 2022)
Data plays a vital role in modern society. With an influx of sensors, data generation is rapidly increasing. Having access to these vast amounts of data enables data-driven decision-making. However, reliable data are needed ...
Developing an electrical cost saving methodology for platinum plant auxiliary systems
(North-West University (South Africa)., 2022)
The mining of platinum group metals (PGMs) contributes significantly to the South African economy. In 2020, the revenue generated from PGM mining accounted for 2.3% of the country’s total gross domestic product (GDP) (R ...
