Other underground coal mines are laid out in a checkerboard of rooms and pillars (Fig. 2), and the mining operation involves cyclical, step by-step mining sequences. The rooms are the empty areas from which coal has been mined, and the pillars are blocks of coal (generally 40 to 80 feet on a side) left to support the mine roof.
