Continuous bolter miners

Sandvik MB-series bolter miners are electrically powered, track-mounted continuous mining machines designed to excavate roadways and install roof bolts simultaneously. Used to drive gate-road entries into coal or mineral seams to form panels for longwall mining, as well as for direct production in room-and-pillar operations, they eliminate the need for machine place-change. Simultaneous cutting and bolting greatly speeds up both development and production, giving substantial economic and safety benefits.
Continuous bolter miners Former name: Alpine Bolter Miner ABM Sandvik MB-series bolter miners are safer, uniquely efficient, high-capacity solutions for both rapid entry development in longwall mining and full-scale production in room-and-pillar mining. The cutter drum is mounted on a hydraulically actuated sliding frame, enabling sumping into the face independently of the mainframe and tracks. Since the roof and rib bolters are mounted on the stationary mainframe, they can be operated throughout the cutting cycle.
