Applying multi-criteria decision-making processes to deep-level mine ventilation projects
(North-West University (South Africa)., 2023)Deep-level underground mining costs in South Africa are continuously rising due to the increased depth at which gold is being mined, increasing the need for improved cooling requirements. Therefore, mines must evaluate ... -
Assessment of the national DSM potential in mine underground services
(North-West University, 2003)ESKOM is moving towards a price structure for electricity which reflects, as far as possible, the real cost of generation. It is called real time pricing (RTP). ESKOM developed this cost structure to coax customers to ... -
Developing a digital twin for addressing complex mine ventilation problems
(North-West University (South Africa), 2021)The ventilation system of a deep-level mine is complex and dynamic, which makes it challenging to identify changes in such a system and even more so to predict the effect of these changes with conventional approaches. An ... -
An integrated energy efficiency strategy for deep mine ventilation and refrigeration
(2014)South Africa’s electricity supply is under pressure. Mining is one of South Africa’s largest electricity consumers with electricity-intensive services such as compressed air, cooling, ventilation, etc. More than 40% of ... -
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 ... -
Optimisation of mine secondary fan systems
(North-West University (South Africa)., 2020)The rising cost of electricity in South Africa has driven deep-level gold mines to save on costs. The optimisation of mine ventilation systems has shown significant potential for energy savings. A literature study showed ...
