Mining - Underground mining | Britannica

The openings made in the process of extracting ore are called stopes or rooms. There are two steps involved in stoping. 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, so that every effort is made to maximize the amount of stoping for a given amount …
