A number of auxiliary materials handling operations are also considered a branch of mineral processing such as storage (as in bin design), conveying, sampling, weighing, slurry transport, and pneumatic transport. The efficiency and efficacy of many processing techniques are influenced by upstream activities such as mining method and blending.
Other articles where Stope is discussed: mining: Underground mining: …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…

Mar 07, 2016· Underground coal and potash mines that were not too deep can sometimes produce sink holes in the overlying ground. Mines that use "room and pillar" mining methods are susceptible to the collapse of the overlying strata which then causes a sinkhole at the surface. The eastern U.S. coal states are prone to this kind of collapse and you can even buy insurance against this happening!

The four stages in coal formation are peat, lignite, bituminous and anthracite. Each of these stages must be completed for coal to form. Stage one in coal production is peat. Peat is a fibrous substance that is oxidized by water and carbon dioxide. When a plant dies, and stays under water, it builds up an accumulation of peat.
