Dec 15, 2017 In room and pillar mining, seams of coal are partially mined, leaving large pillars of coal intact to support the overlying layers of rock. When finished, miners practice “retreat” mining, extracting as much coal as possible from the remaining pillars as they reverse their way out, allowing the roof of the seam to collapse.
