40 ratings | 20079 views
The room & pillar mining method is used predominantly for underground coal deposits, however also for potash deposits. Coal is not completely being mined out from the underground deposit, but pillars are left standing to keep the roof from caving in. Caterpillar offers a complete range of machinery for this mining method. The extensive room & pillar product line includes a seamless range of continuous miners, face haulers, continuous haulage systems, feeder breakers, roof bolters as well as a broad range of battery- and diesel-driven utility vehicles like scoops and LHD vehicles.
