Continuous Miners For Cutting Coal & Soft Materials ...
Continuous miners cut and gather the material simultaneously and convey it into shuttle cars, haul trucks or a continuous haulage system. They are typically used for full-scale production in room-and-pillar mining operations. The flameproof design of these machines is certified according to national regulations, such as MSHA (USA), SANS (South Africa) and DGMS (India).
