12. (1)Room-and-pillar mining method: • Room-and-pillar mining is very old method applied to horizontal or nearly horizontal deposits that has been adopted and refined over the years. The method is used in both coal and non coal mining. • In room-and-pillar mining openings are driven orthogonally and at regular intervals in a mineral deposit,forming rectangular and …
In the longwall mining method, mine development is carried out in such a manner that large blocks of coal, usually 100 to 300 metres wide and 1,000 to 3,000 metres long, are available for complete extraction (see photograph).A block of coal is extracted in slices, the dimensions of which are fixed by the height of coal extracted, the width of the longwall face, …

coal reserves from deep underground seams. The chapter discusses: three surface mining techniques that are used in the West: 1) area strip, 2) open pit, and 3) terrace pit; two methods of underground mining in the West: 1) room and pillar with contin-uous miners, and 2) longwall mining; recent underground mining technology
Current underground mining methods can be classified into three main groups, namely: (a) naturally-supported, (b) artificially-supported, and (c) unsupported (Fig. 3; Brady and Brown, 2006). Naturally-supported mining methods leave a portion of unmined ore as pillars, commonly referred to as remnant pillars.
The mining method selection for underground mining is one of the most important decisions when designing a mine. This selection depends on the mining-geological, mining-technical and economic factors.
