Physics of Coal and Mining Processes by Anatoly D. …

Coal is extracted from the ground with a process called mining. Coal Mining can be of two types: 1. Opencast Mining: Mining in which coal is extracted from near the earth’s surface. 2. Underground Mining: Mining in which coal is extracted from deep inside the earth’s crust. Different Types Coal As coal gets older, the carbon content in it ...

Opencast mining is also known as open-put mining, open-cut mining, surface mining and also as strip mining, the later term being commonly used in the U.S.A. for opencast mining of coal. The overburden and the mineral, coal, are excavated in long strips of a few metres thickness and hence the operations are termed strip mining.

The action of the pressure and heat of the Earths crust over millions of years converts the fossilised remains of these plants into coal. Coal is mined from coal seams in the Earth’s crust. Where the coal is near the surface of the Earth, open cast mining is used but in areas where the seam is deep underground mining is used to extract the coal.

One of the methods used in underground mining is called room and pillar, and is often used for mining coal. Part of the mine is open to the surface and part of it is underground. The coal face is dug out, but pillars of coal are left behind to keep the tunnels open and support the roof. Machines called continuous miners are used to remove the coal.
