♦ Coal miners have been working for centuries, but during the Industrial Revolution from 1760 to 1840, coal mines became very important, when coal was used on a large scale to heat stationery and locomotive engines and to heat buildings. Coal is a natural resource that promotes economic and social development.
♦ Coal mining started in the year 1774 in India when John Summer and Suetonius Grant Heatly of the East India Company began commercial exploration along the Raniganj coalfield on the west bank of the Damodar River.
