Coal mining is the extraction of coal from deposits found either near the surface of the earth or underground. Coal is a fossil fuel, a nonrenewable (available in limited quantities) fuel source. Coal consists of hydrogen, oxygen, carbon, sulfur, and other trace elements. A coal reserve is a deposit of coal that can be mined.

Shaft mining is a form of underground mining where shafts are pushed vertically from top to bottom to excavate the ores and minerals. It is also called shaft sinking. It is best suited for concentrated minerals such as iron, coal, etc. which can be found at the depth of the earth's surface. It is found mostly all over the world.
