conditions in real time. Within excavation itself, drilling equipment is increasingly equipped with LiDAR and digital mapping technologies. “Every metre of advancement can be scanned, mapped, and compared against geological models. Any deviation or unexpected condition is identified almost immediately, allowing teams to respond proactively. These systems are integrated with mine survey networks and digital planning platforms, enabling highly automated drilling operations. In many cases, drilling equipment can execute planned development and production drilling with minimal operator intervention. Similar technologies are already widely used in tunnelling operations and production drilling for open stoping mines. The ability to remotely operate underground equipment from anywhere in the world has existed for some time. The next stage of development is the continued advancement of automation, artificial intelligence and autonomous mining systems, further reducing risk while improving productivity and precision,” says Chamberlain. Efficiency and safety The mining industry has made substantial gains in efficiency by progressively reducing the size of shaft-sinking crews, says Chamberlain; however, while these efficiencies have streamlined operations, they have been accompanied by some decline in production rates as more stringent safety protocols and work practices have become standard across the sector. “Historically, shaft-sinking projects achieved records of up to 120 metres per month. Today, industry averages are typically in the range of 50 to 60 metres per month for blind sinking projects. While this may appear less efficient, it reflects the reality that modern shaft sinking places a much greater emphasis on safety, risk management, and controlled work practices.” Cementation Africa is actively exploring ways to reintroduce some of the highly productive technologies used historically, but within a modern safety framework. “A good example is the cactus grab. This equipment was once one of the most efficient tools available for shaft sinking, particularly for mucking and cleaning operations. However, it was also associated with several serious incidents and fatalities, which ultimately led to its removal from use. Our focus is on how to safely reintroduce that level of productivity. By mounting cactus grabs on rigid booms and integrating remote-control technology, we believe it is possible to achieve the efficiency benefits while eliminating many of the historical safety risks. We have already developed and implemented solid-boom systems, and the next step is to combine these technologies into a safer,

The combination of mechanisation, automation, remote operation, and advanced safety systems will ultimately shape the future of shaft sinking and raise boring, and we intend to remain at the forefront of that evolution.” n
