Mining. Coal is extracted by two principal methods, of which there are many variants: surface mining or subsurface mining. Surface mining uses large machines to remove the soil and layers of rock known as overburden to expose coal seams that are close to the Earth's surface (figure (PageIndex{a})).Strip mining is a type of surface mining in …

Open-pit is one of the most common mining methods used and starts from the earth's surface, maintaining exposure to the surface throughout the extraction period. The excavation usually has stepped sides to ensure the safety of the miners and a wide ramp where equipment can travel, allowing the product to be removed efficiently from the site.

In room and pillar mining, coal deposits are mined by creating a network of rooms into the coal seam. Pillars of coal are left at the site to support the roof. In case of continuous mining, a Continuous Miner Machine is used to break off the coal from the seam. The coal removed from the seam will be later transported using conveyors.
