Room and pillar mining Wikipedia
Room and pillar (variant of breast stoping), is a mining system in which the mined material is extracted across a horizontal plane, creating horizontal arrays of rooms and pillars. To do this, "rooms" of ore are dug out while "pillars" of untouched material are left to support the roof overburden. Calculating the size, shape, and position of pillars is a complicated procedure, and is an area of active research. The technique is usually used for relatively flat-lying deposits, such as those that follow a particular stratum.

Stope mining Britannica
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

Geotechnical approach to stope and pillar optimisation at
Mining methods at GSGM are based on variations of a longhole open stope and room and pillar method. There is no planned backfill. This methodology was originally proposed due to the flat lying nature of the ore lodes. The mining methods used are: Inclined room and pillar. Transverse longhole open stoping. Longhole wall slash.

Designing an optimal stope layout for underground mining
Sep 01, 2015 An illustration of the stope and pillar layout notations. Moreover, if a mining block is shared among a number of possible stopes, i.e. the mining block exists in more than one stope sets, such combinations are categorized as overlapping stopes. Physical mining constraint restricts the generation of overlapping stopes, and accordingly, avoiding

(PDF) Rib pillar design in open stope mining
The approach involves an empirical method for pillar design and a discusion of the pillar stability used for open stope mining methods. The empirical method predicts the stability of rib pillars.

Underground Mining Methods EXCELLENCE IN MINING
Jul 21, 2016 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
