In the coke oven, the coal is heated to 1,800°F for up to 18 hours. During that time, the volatiles of the coal are driven into the offgas and a pure carbon form called "coke" remains. The coke, when exposed to oxygen, will immediately ignite and begin to burn.

Methods of coal mining depend on the depth of its occurrence. Open-pit coal mining is used, if the depth of the coal seam does not exceed 100 meters. There are also cases when it becomes more profitable to excavate coal deposits by the underground mining method as the coal quarry deepens. Coal mines are used to extract coal from the depths.

Coke is made by baking coking coal, also called metallurgical coal, in special high-temperature ovens to remove non-carbon elements and compounds. The resulting coke is mostly carbon. Coking coal must be low in sulfur and requires more thorough cleaning than coal used in power plants, which makes the coal more expensive.
