Sandvik MB670-1 FLP bolter miner excels in longwall coal mining. It cuts, supports and gathers the material simultaneously. It then conveys it into shuttle cars, coal haulers, or a continuous haulage system, ready for transport.
Features
-
Cutting and bolting in one machine
While the machine is stabilized for installing the ground support, the sump frame mechanism, which incorporates cutting and bolting into a single machine, continues to move forward to cut out the next cycle, enhancing productivity.
-
Faster advance cycles
Sandvik MB670-1 features semi-automatic bolting and an adaptable auto-cutting cycle, enabling faster advance cycles. This reduces panel development times by up to 30% and ensures smoother floor conditions in your mine.
-
Less wear on shuttle cars
Horizon control lead means shuttle cars see less wear-and-tear and floor conditions are improved.
