mining‖ and ―pillar recovery‖ will also be used interchangeably. When room-and-pillar methods are employed, large blocks of coal in the form of pillars are initially left in place to support the great weight of the overburden (cover). Unless these pillars are subsequently extracted, the coal they contain can never be recovered.

Surface Mining When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast or open pit) mining methods. Strip mining is typically used for coal. Strip mining exposes the coal by the advancement of a moving open pit or strip. The earth above the coal is known as overburden.

Early coal extraction was small-scale, the coal lying either on the surface, or very close to it. Typical methods for extraction included drift mining and bell pits.As well as drift mines, small scale shaft mining was used. This took the form of a bell pit, the extraction working outward from a central shaft, or a technique called room and pillar in which 'rooms' of coal were extracted …
