Most trona is mined through a room-and-pillar system where a series of parallel drifts are driven. Connections are made between the drifts at regular intervals, which creates a checkerboard pattern of rooms and pillars. The pillars are left to support the overlying rock, and the mineral is then cut from the mining face and processed.
