RoomandPillar Mining. In the roomandpillar method, a set of entries, usually between three and eight, are driven into a block of coal. These entries are connected by crosscuts, which are usually at right angle to the entries. The entries are commonly spaced from 50 to 100 feet apart, and the crosscuts are usually about 50 to 150 feet apart.
