The hard-rock mining industry faces persistent challenges of deep-level extraction, volatile commodity markets, and rising expectations for worker safety and environmental stewardship. These pressures have accelerated interest in “smart mining”, which entails the integration of emerging technologies (ETs) such as advanced sensing, autonomous equipment, robotics, artificial intelligence, digital twins, wearable technologies and real-time analytics. These technologies are designed to transform and revolutionise the conventional method of locating, mining and processing ore bodies. This paper critically examines the strategic benefits of technology uptake in deep-level hard-rock operations, demonstrating how smart mining enhances safety, productivity, and sustainability while strengthening long-term competitiveness. The study employed a structured, closed-ended questionnaire survey administered to highly experienced mining professionals in the South African hard-rock mining sector. The retrieved data were subjected to descriptive analysis. Findings revealed that reduced human exposure to hazardous environments, safety promotion, improved productivity, enhanced robust data analysis, easy data transfer, and optimised scheduling processes are the top benefits of adopting ETs. Therefore, the transition to smart mining presents a compelling strategy for deep-level hard-rock operations seeking to balance productivity imperatives with worker welfare and environmental responsibility. Hence, the South African experience underscores the broader global potential of emerging mining technologies to deliver safer workplaces, enhanced resource efficiency, and sustainable growth for the sector.
