    The room-and-pillar involves extracting the rock by carving a series of rooms while leaving pillars of rock to support the mine roof. When mining reaches the end of a section of deposit called a panel, the direction of mining is generally reversed (called the “retreat”) in an attempt to recover as much of the rock from the pillars as possible.

    Room and pillar mining often leads to retreat mining, in which supporting pillars are removed as miners retreat, allowing the room to cave in, thereby loosening more ore.
