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 underground mining methods we use include room and pillar, narrow vein stoping and largescale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.
The first full fleet of Cat branded roomandpillar coal mining equipment is being installed by Armstrong Coal in conjunction with the opening of its new underground mine at Creek in Kentucky. The mining company, a subsidiary of Armstrong Energy, purchased 24 machines from Cat dealer Whayne Supply following the dealerships acquisition of the former Bucyrus distribution and product support business.

In roomandpillar systems, electricpowered, rubbertired vehicles called shuttle cars haul coal from the face to the intermediate haulage system. In some semimechanized or manual longwall operations, chain haulage is used, while the face haulage equipment of choice in modern mechanized longwall systems is an armoured face conveyor (AFC).
Both room and pillar and longwall mining are mostly now performed with very powerful mining machines, which rapidly cut coal from the face of coal seams. These machines are phasing out the use of less productive and more dangerous traditional methods, which require intermittently drilling the coal seam and blasting it with explosives.
