Bolter miners

 

Sandvik 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.
