Coal and railways
In 1774, Suetonius Heatly and John Sumner of the British East India Companyrealised that local people were using coal in the region of which Asansol is a part. Their early explorations and mining operations were carried out in a haphazard manner and demand was limited. Regular mining operations started in 1820, led by an agency house, Alexander and Co. In 1835, Prince Dwarkanath Tagore bought over the collieries and Carr and Tagore Co. led the field. For the entire 19th century and a major part of the 20th century, Ranigunj coalfields in the Asansol region was the major producer of coal in the country.
