    Room-and-pillar mining is typically chosen for flat-lying (or at slightly dipping) ore bodies. Commonly used for base metal or uranium metal deposits, or bedded seams of coal/potash/salt, mining is done by creating openings (rooms) on a single level, leaving pillars of rock at regular intervals to support the weight of the material above (the .

    Stope-and-pillar mining (a stope is a production opening in a metal mine) is a similar method used in non-coal mines where thicker, more irregular ore bodies occur; the pillars are spaced randomly and located in low-grade ore so that the high-grade ore can be extracted. These two methods account for almost all of the underground mining in .

The first is development—that is, preparing the ore blocks for mining—and the second is production, or stoping, itself. Ore development is generally much more expensive on a per-ton basis than stoping.
