automated machine its own space. “To deal with situations like this, machines need artificial intelligence (AI); we have launched our AutoMine concept loader and underground drill rig, which are AI-enabled and fully autonomous,” Nkoana explains. “This concept includes perception-sensing technologies to detect obstacles, and make deci sions about their movements when there is a person in their proximity.” He highlights that the application of technological change needs to be carefully managed at site level, with the involvement and education of all stakehold ers. Sandvik Mining and Rock Solutions makes a point of guiding customers through the process of automation, planning each step and ensuring the necessary skills development and commitment. 

essentially replicates the OEM’s machine control system to enable remote control over the Wi-Fi net work,” he says. “This enhances safety especially when rigs are operating close to a highwall, or when there are unstable geological conditions on the bench. Mines have embraced these features to fur ther enhance the safety of operators.” The automation of this equipment is also paying dividends in terms of reliability and performance. This is due to the machines’ extensive sensing capa bility, where they are picking up valuable data about their working environment. Programmed to oper ate only within their design limits, they will respond immediately to changes. “An automated machine will follow pre-deter mined instructions and will not exceed its limitations,” says Nkoana. “This helps extend the life of consum ables and components, generally leading to a lower total cost of ownership.” Interoperability He notes that Sandvik Mining and Rock Solutions is continually developing its digital offerings in response to customer preferences and needs. As the mining sector evolves toward ‘smart’ operations, one of the key imperatives for an OEM is to ensure the interoperability of its technology. “Mines will usually have a range of OEM brands on their site, but they are working towards greater transparency of all operations through integrating data from different sources,” he says. “Management on mines therefore needs the third-party systems to speak to each other – so we have achieved a high level of interoperability and continue to develop our systems in this direction.” Geo-fencing The trend towards automation on mines means that automated equipment is increasingly sharing the physical space occupied by manually operated machines on a site. To ensure the highest levels of safety, automated machines can be ‘geo-fenced’ – or partitioned off – from manual equipment. However, he points out that there are also situ ations where the area is too confined to give the

Above: AutoMine ® essentially replicates the machine control system to enable remote control over the mine’s Wi-Fi network. Right: Without an operator being present in the actual working area, the equipment can be kept working during blast clearance and shift changes.
