Coalmining in India first started in the Raniganj Coalfield. In 1774, John Sumner and Suetonius Grant Heatly of the British East India Company found coal near Ethora, presently in Salanpur community development block. The early exploration and mining operations were carried out in a haphazard manner. [1]
The terminology declined into unimportance as the 20th century progressed, and was probably only referred to by a few small railroads and history buffs by the 1980s. Renewed interest in industrial heritage and coal mining history has brought the old names of the coalfields before a larger audience.
Coal in India has been mined since 1774, and India is the second largest producer and consumer of coal after China, mining 997 million metric tons (1,099 million short tons) in FY 2023-24. Around 20% of coal is imported.
Jharia coalfield is a large coal field located in the east of India in Jharia, Dhanbad, Jharkhand. Jharia represents the largest coal reserves in India having estimated reserves of 19.4 billion tonnes of coking coal. [1] The coalfield is an important contributor to the local economy, employing much of the local population either directly or ...
Outside the Damodar Valley, Satpura Gondwana Basin is the only area where coking coal is found in India. [2] [3] The Pench Kanhan Valley Coalfield is situated 30 km (19 mi) to the northwest of Chhindwara. While Pench Valley has five seams in a column of 50-80 m thickness, the coal belt in the Kanhan valley stretches for about 25 km (16 mi).
Coal mining activities were initiated in Giridih by private owners in 1857, making it the earliest coal mine in Bihar/Jharkhand. East Indian Railway started organised mining in 1896. The ownership of the coalfield was handed over to the state collieries in 1936 and then transferred to National Coal Development Corporation in 1956.
The coal field lies in the Damodar River Valley, and covers about 110 square miles (280 square km), and produces bituminous coal suitable for coke. Most of India's coal comes from Jharia. Jharia coal mines are India's most important storehouse [18] of prime coke coal used in blast furnaces, it consists of 23 large underground and nine large ...
According to the Geological Survey of India, Godavari Valley Coalfield has total reserves (as on 1 January 2004) of 16,697.26 million tonnes of non-coking coal, up to a depth of 1,200 m, out of which 8091.10 million tonnes are proved reserves and the rest being indicated or inferred. A large portion of the coal is up to a depth of 300 m. [4]
