Underwater Mining Crawler
Extend your life of mine
Originated from deep sea mining and trenching systems, the Underwater Mining Crawler is a remote-controlled vehicle, equipped with the latest underwater control and positioning equipment, that will maximise your life of mine and reduce the footprint of your mining operation.
With its powerful drum cutter, integrated cutterspecial® slurry pump and Hi-Traq® propulsion system the crawler can reach deeper and more complex ore deposits and mine any small corner of any size mining pit, from small kimberlite pipes to the open ocean.
Benefits
- operates in mines previously unreachable with conventional mining equipment
- extends life of mine of underwater deposits, both on-land and offshore
- improved productivity through continuous and accurate mining
- no need for dewatering the pit,
- allows for steeper side walls, improving the waste/ore ratio
- remotely operated, keeping staff safe and away from the mining area.
Combining crawler with launch and recovery system: an integrated mining solution on- or offshore
The crawler requires a launch and recovery system (LARS) for it to operate properly.
In an onshore setting the crawler will be launched, recovered and maintained from a dedicated floating platform. Control cabin, power supply and dewatering plant can be positioned conveniently on land. Allowing personnel to stay safe while the crawler follows the mine plan.
In an offshore setting a vessel will serve as the integrated mining platform. Depending on the vessel this integrated system of crawler and launch and recovery system can operate up to Seastate 4.
Mined material is pumped from the crawler to the surface through a vertical flexible pipe, using water jets to create a slurry flow. The slurry can then be pumped further to a land-based dewatering plant or remain on board for further transport or processing.
