The history of coal mining goes back thousands of years, with early mines documented in ancient China, the Roman Empire and other early historical economies. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity. . Coal mining continues as an important economic activity today

Mined in various parts of the world, coal mining continues to be an important economic activity and at present, over 6185 million tonnes (Mt) of hard coal is produced worldwide. Extraction methods Based on the quality of the seams and depth, together with geology and environmental factors, economical method of extraction is considered from coal seams.

underground coal mining: see coal mining coal mining,physical extraction of coal resources to yield coal; also, the business of exploring for, developing, mining, and transporting coal in any form. Coal has been historically important industrially as a source of energy

The two major types of coal extraction are surface mining and underground mining. In surface mining, soil and rock over the coal seam are removed to expose the coal, which is fragmented and removed. Underground mining involves accessing a coal seam by suitable openings from the surface, called shafts, slopes, or drifts.
