Coal Mining

Coal mining is the process of extracting coal from the ground. Coal, since the 1880s, has been widely used to generate electricity. As one kind of energy, steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. Coal is the most abundant fossil fuel on Earth.
