Stoping - Wikipedia

When the ore body is more or less horizontal, various forms of room and pillar stoping, cut and fill, or longwall mining can take place. In steeply-dipping ore bodies, such as lodes of tin, the stopes become long narrow near-vertical spaces, which, if one reaches the surface is known as a gunnis or coffen. A common method of mining such ...

Ore Body - an overview | ScienceDirect Topics

Suppose that an ore body with electronic conductivity is surrounded by sedimentary rock whose conductivity is dominated by ions in its water-filled pores, and that part of the body extends above the water table. The surface of the ore body below the water table is a boundary between media with different mechanisms of conductivity (electronic and ionic), and a natural electrochemical reaction ...

Mining - Underground mining | Britannica

Mining - Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the ...

All Categories - Mining Methods

The three most frequent surface mining methods are generally strip mining, terrace exploration and open pit exploration. Strip mining is if at all possible applied where the surface of the terrain and the ore body itself are generally relatively horizontal and not way too deep under the surface and a wide area is available to be mined in a series of whitening strips.
