Epiroc has partnered with Fortescue in Western Australia to test and evaluate the autonomous SmartROC D65 MKII. The surface drill rig has shown outstanding results during the testing phase, including increased productive utilisation - in autonomous mode, the drill rig has zero idling time during transitions between tramming, positioning and drilling, which provides consistent efficiency in every hole cycle and reduces the total time spent to complete a drill pattern.

"We are very excited about the progress we have seen over the last year together with our partner Fortescue. The market has been eager to see what benefits this new technology can bring to mining operations, so this is an important milestone - both for autonomous drilling in general and for Epiroc as a company," Christopher Blignaut, automation manager, Surface division, said.

"Throughout testing, the autonomous SmartROC D65 MKII rig consistently achieved hole accuracy targets set beyond what was achievable with manual operations. The benefits of this can be seen through more efficient drilling and blasting results."

Pit Viper

The autonomous journey for Epiroc goes back to 2014 when the first autonomous Pit Viper drill was released. Further advancement occurred in 2018 when Epiroc commenced a pilot project with an autonomous SmartROC D65 MKI surface crawler in Timmins, Canada. During this period, the team acquired extensive understanding and expertise in autonomous technology development for crawler drill rigs.

"During our previous projects we have gained extensive knowledge and experience which we have used throughout the development of the autonomous technology. The success that we accumulated from the project in Timmins was fundamental to the results that we see today with the autonomous SmartROC D65 MKII in Australia," Blignaut said.

The focus for the testing thus far has been targeting production drilling applications. "Together with Fortescue, we will progress to testing autonomous pre-split drilling and eventually focus on even more complex drilling scenarios, like contour," Blignaut added.

We see increasing interest in autonomous operations thanks to the numerous benefits it provides

"In our conversations with the mining houses globally, we see increasing interest in autonomous operations thanks to the numerous benefits it provides, and we are dedicated to supporting these companies by introducing the Autonomous SmartROC D65 MKII into their drilling operations. Autonomous technology implementation capitalises even further from adjustments to existing processes and a transition to new ways of working. At Epiroc, we are ready to support our business partners in accelerating this transformation," Mayya Popova, product manager automation at Epiroc, said.
