COAL MINING 009: In roomandpillar mining, this method is more preferred than the conventional mining method because separate unit operations are eliminated or performed by a single highperformance mining machine. It is also more efficient than the latter, lends more easily to, and benefits from simulation analyses for improving its performance.
Room and pillar mining was one of the earliest methods used, although with significantly more manpower. The room and pillar system is used in mining coal, gypsum, iron, and uranium ores, particularly when found as manto or blanket deposits, stone and aggregates, talc, soda ash and potash.

The 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 down.
The objective of this study is to apply a simulation tool to evaluate if optimizing support systems, such as cutout distance, fleet size, and panel dimensions, can maximize CM utilization and productivity. Discrete event simulation is used to analyze different cutout distances for a room and pillar mining system.
