Roomandpillar mining generally is limited to depths of about 1,000 feet because at greater depths larger pillars are needed, resulting in smaller coal recovery (typically 60% of the coal in the affected area). The "continuous" version of roomand pillar mining is the most common, representing more than half of all underground production.

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.
Room and Pillar Mining is Safe, Efficient Environmentally Friendly. Room and pillar mining is a nonsubsidence plan for a mine, preserving the precious farmland is among the safest and one of the most ecologicallyfriendly approaches to mining coal today, creating a nonsubsidence environment (no movement of land) and maintaining clean water standards.

Some sources provided are very old. However, due to the more historic nature of room and pillar mining, this is acceptable. I have also cited one coal company (Sunrise Coal LLC) but I am discussing ways in which coal mining is done, and as companies are somewhat protective of their methods, this is the primary and most extensive source I can ...
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.
