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 ... -
Evaluating water supply control at a centralised hydro-powered mine
(North-West University (South Africa), 2021)Deep-level mines face economic challenges which comprise reducing operating costs while increasing production. Hydro-powered mining was developed as an alternative mining method to conventional pneumatically-powered mining ... -
Expanding compressed air demand side management through selective level control
(North-West University (South Africa)., 2022)Compressed air is a resource which is used across the deep-level mining industry for a variety of purposes throughout the 24-hour mining cycle. It has been noted that compressed air is a particularly inefficient source ... -
Geohydrological consequences associated with the post-mine closure flooding of dewatered dolomitic karst aquifers in the Far West Rand, South Africa
(North-West University (South Africa), 2015)English The thesis presents a hydrologic investigation into the effects of deep-level gold mining on the hydrogeological conditions of a fractured-karst aquifer system in the Far West Rand (FWR) goldfield, South Africa. ... -
Modeling power failures in deep-level mines to assist with emergency dewatering planning
(North-West University (South Africa)., 2023)A mining complex’s intricate dewatering system removes water that enters the shaft through various means. This system comprises a series of water pumps that require a constant power supply to avoid flooding key areas of ... -
Using impacts of deep-level mining to research karst hydrology—a Darcy-based approach to predict the future of dried-up dolomitic springs in the Far West Rand goldfield (SouthAfrica). Part 2: predicting inter-compartmental flow and final groundwater tables
(Springer, 2014)Some of the world’s deepest goldmines operate below dolomitic karst aquifers in the Far West Rand (FWR) goldfield, South Africa. Associated impacts include the continuous dewatering of karst aquifers for over six decades ...
