  • 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.

    Consequently, a drift (adit) was driven into the quarry face to follow the Gypsum deposit and the extraction method switched to mining using pillar and stall methods. Meanwhile since 1879 Howe Co. had sunk several exploratory shafts to confirm the presence of Gypsum in the locality of Cocklakes Quarry and by 1890 a large adit was driven into the north face of the quarry and pillar and stall

  • Research on Catastrophic Pillar Instability in Room

    Gypsum mines in China are mostly exploited through room and pillar mining. Due to backward mining technology and a long history of mining, a great number of pillars were left in gypsum mines. Many serious work safety accidents occurred as the result of goaf instability in history, which posed severe threats to the security of peoplersquo;s lives and property.

    01-11-2020  For example, the Hartley Colliery located just inland from the studied section [NZ 301 771], worked the High Main and Yard seams primarily by pillar and stall methods, and the Five Quarter seam initially by pillar and stall methods, followed by later longwall mining. The undermining of pillar and stall workings affects the local stress regime in the mine, and will impact the location and extent of

Gypsum is produced from open-cast mines, or underground mines using pillar and stall mining methods. For cement manufacturing process, Gypsum is supplied in crushed form for further fine grinding with clinker.

    DP: "There are actually five British gypsum mines, three of which are drill-and-blast and two of which use continuous mining machines. Brightling is a drill-and-blast operation that adopts a 'room-and-pillar' mining method using two twin-boom drill rigs supplied by the former British company Torque Tension, which also supplied bespoke charging machines for charging the faces."
