The Cat® Rock Straight System is a fully mechanized longwall system adopted to hard rock conditions for continuous mining of low seam hard rock deposits. The Rock Straight System combines the use of a hard rock shearer (Hard Rock Miner HRM220), a hard rock chain conveyor (Hard Rock Conveyor HRC30) and hydraulic roof support (Hard Rock Roof Support HRS1220). It features the unique adaptation of Caterpillar “Activated Undercutting Technology” and has been specifically designed for the extraction of bedded hard rock deposits (e.g. platinum, copper, gold). The Rock Straight System provides economical cutting in the mining of thin seams and narrow veins, especially when selective mining of ore is required.
