Early Mining Methods

 · Bell Pit Mining. Bell pit mining was one of the early methods of underground mining. The name comes from the shape that the mine forms. A long narrow shaft is dug down until it reaches the coal seam. Once it reaches the seam, the coal is then mined laterally along the seam either side of the shaft, creating the bell shape.

History of coal mining

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 with ...
