Coal Mining is the term that encompasses the physical extraction or removal of coal from the Earth’s Surface. When coal is used as fuel in power generation, it is referred to as Steaming or Thermal coal while those which are used to create coke for steel manufacturing is referred to as Coking or Metallurgical Coal. Coal can be mined by both Surface and Underground Mining methods. Surface,3 Methods of Coal Mining - EzineArticles,o Blast: An older mining method that uses dynamite and explosives to break away the coal seam. Accounts for less than 5% of coal production. o Retreat Mining: One of the most dangerous coal mining methods. Pillars are used to hold up the mine roof as coal is extracted.coal mining | Definition, History, Types, & Facts | Britannica,23-11-2020· The conventional mining techniques described above, made up of the cyclic operations of cutting, drilling, blasting, and loading, developed in association with room-and-pillar mining.The oldest of the basic underground methods, room-and-pillar mining grew naturally out of the need to recover more coal as mining operations became deeper and more expensive.

Methods of Coal Mining - EzineArticles

Surface mining is used for about 40% of coal production in the world. When coal deposits are near the surface, it may be inexpensive to extract the coal using this method. The different types of surface mining are strip, contour, and mountaintop removal mining.Coal Mining Methods in the East of Scotland,Coal Mining Methods 'Pillar and Stoop' was the method used for a long time until in the 19th century, the modern longwall method became widespread. Pillar and Stoop - coal was removed in a grid like way leaving large pillars of coal untouched to support the roof of the seam.History of coal mining - Wikipedia,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,
