Sandvik Mining and Rock Solutions has introduced its AutoMine Concept Underground Drill, the company’s second technology demonstrator for its future autonomous mining vision.
The AutoMine Concept Underground Drill is a fully autonomous, twin-boom development drill rig capable of drilling without human interaction. The cabinless battery-electric drill can plan and execute the entire drilling cycle from tramming to the face, setting up for drilling, drilling the pattern and returning home to charge for the next cycle.
Less than two years after introducing the AutoMine Concept Loader – the first fully autonomous underground mining machine built specifically for automation – Sandvik has expanded its vision from autonomous mucking to autonomous drilling with its AutoMine Concept Underground Drill.
“We’re continuing to push the boundaries of mining automation and demonstrate what will be the reality in the near future,” said Sandvik Mining and Rock Solutions VP for automation David Hallett.
“We chose a development drill as our next concept vehicle to demonstrate that autonomy can also work effectively in a mine’s development phase, in constantly changing environments.”
Unveiled and demonstrated for the first time at a customer event at Sandvik Mining and Rock Solutions’ test mine in Tampere, Finland, the fully functional AutoMine Concept Underground Drill, referred to internally during the lead-up to its introduction as “Amelia,” showcases next-generation intelligent automation and other new technologies and features that will be introduced for current and future Sandvik offerings.
Some features will be available as standalone products and others as upgrades or options for existing products or equipment.
“Our AutoMine Concept Underground Drill is not intended to be introduced as a commercial product,” said Sandvik Mining and Rock Solutions product development and product management VP Johannes Välivaara.
“Rather, it will become our in-house platform for testing and developing new technologies our customers identify as crucial to their operations.”
The AutoMine Concept Underground Drill has no operator cabin, creating space for onboard water and battery storage and eliminating the need for supply cables or water hoses during operation. The self-contained drill uses and optimizes power and electricity based on need, making onboard supply last even longer.
The drill only needs to know which tunnel and face it should tram to and can plan the rest of its mission autonomously, using data from the preferred mine planning software. Tunnel lines and profiles are planned and defined into drilling and blasting patterns in iSURE that ensure optimal hole placement, detonation, and profile quality.
The drill also has access to three-dimensional (3D) models of a site, which are automatically merged from survey and mapping results. It can update and optimize the 3D model of the mine in real time based on feedback from its onboard cameras and scanners.
The drill learns and adapts to the ever-changing environment in a development heading to safely complete entire missions from entry to exit. It navigates tight spaces with agility, enabling effective use of large machines in small spaces. Once it has arrived at its destination, it uses automatic drill plan adjustment to optimize the drilling pattern and drill the full round.
“Our vision is that in the near future, thanks to the rapid advancement of battery technologies, equipment like this will be able to drill entire rounds fully on battery power, eliminating the need to plug in to a grid and improving flexibility underground,” Sandvik Mining and Rock Solutions digitalization research lead Jussi Puura commented.
During drilling, the AutoMine® Concept Underground Drill uses an artificial intelligence- (AI-) guided automatic drill bit changer to identify when bits are worn and changes them automatically. The drill is also equipped with a lifter tube installer that simplifies the face charging procedure. Drilling data is then reported back to iSURE or Deswik to optimize the next round. The drill also uses Rock Pulse® AI for continuous rock mass feedback to optimize drilling performance.
The AutoMine® Concept Underground Drill is compatible with traditional safety gate systems but is also capable of working without area isolation. It asks for assistance when re-filling consumables and recharging and can request intervention by an operator if it is unsure of changes to its environment.
