  • Room and Pillar Mining an overview | ScienceDirect Topics

    Continuous miners, used primarily in ‘room and pillar’ mining and also to prepare roadways in a ‘longwall’ systems, have incrementally improved over the last 20 years (Fig 711)But they are not advancing in automation as quickly as longwall equipment, with the exception that they are more often remotely controlled by an operator, rather than by an operator sitting on the machineRoom and pillar For the challenging industrial minerals market, where safety, productivity and low operating costs are paramount, Komatsu offers you a full range of entry development equipment, including heavyduty continuous miners, continuous andRoom and pillar | Komatsu P&H MiningThe room and pillar system is used in mining coal, iron and copper ores mainly when found as manto or blanket sediments, stone and aggregates, talc, soda ash and potash The key to the winning room and pillar mining is opting the optimum pillar size If the pillars are so small the mine will fall downRoom and pillar mines, Mining Techniques, Underground
