Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content.  Coal mining continues as an important economic activity today. Though it was used historically as a domestic fuel, coal is now used mostly in industries. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production.
