Coal mining | World Coal Association

In room-and-pillar mining, coal deposits are mined by cutting a network of rooms into the coal seam and leaving behind pillars of coal to support the roof of the mine. These pillars can be up to 40% of the total coal in the seam - although this coal can sometimes be recovered at a later stage.

Coal mining - Wikipedia

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production.

Refined coal - Wikipedia

The plant uses LCP coal-upgrading technology, which is a pyrolytic process that employs heat and pressure in an oxygen-free environment to continue the coalification process that occurs naturally in the earth. The processed coal by this technology is hydrophobic and transportable, which means it will not reabsorb moisture or break up into powder during transportation.

Mineral processing - Wikipedia

An aqueous solution as a dense medium is used in coal processing in the form of a belknap wash and suspensions in air are used in water-deficient areas, like areas of China, where sand is used to separate coal from the gangue minerals.
