Major Coal Fields in India

As India’s internal earth structure is formed from ancient hard rocks, it is one of the mineral-rich countries in the world. Coal is the main energy source in the country and currently accounts for 54% of the country’s energy needs. About 70% of the energy generated in the country is from coal-based power plants. India has an estimated 326.49 billion metric tonnes of Coal. The coal reserves are mainly found in Jharkhand, Chhattisgarh, Odisha, West Bengal, Madya Pradesh, Maharashtra, and Telangana.

Distribution of Coal in India

Before going to discuss the major coalfields in India, we must know about the categories of coalfields. In India, Coal Fields may be classified into two categories:

  1. Gondwana Coalfields.
  2. Tertiary Coalfields.

Gondwana Coal

The Gondwana coal is basically from the Carboniferous period about 250 million years back. Around 98% of the total coal reserves found in India are from the Gondwana period. The Gondwana coal is mainly of Anthracite or Bituminous type, containing 60 to 90 per cent carbon content. It is found in Damodar (Jharkand-West Bengal), Mahanadi (Chhattisgarh-Odisha), Godavari (Maharashtra), and Narmada valleys.

Tertiary Coal

Tertiary coal is formed from the rocks of the Oligocene period (tertiary era), about 15 to 16 millions year old. It contributes only 2% of the total coal production in India. It is rich in moisture & sulphur but has low carbon content. It is mainly of lignite type, also called brown coal. Important areas where tertiary coal is found are Assam, Meghalaya, Arunachal Pradesh, Nagaland, Jammu and Kashmir, Himalayan foothills of Darjeeling in West Bengal, Uttar Pradesh, Rajasthan, and Kerala.

Distribution of Gondwana Coal in India

Major states having large coal reserves of Gondwana coal are Jharkhand, Odisha, West Bengal, Chhattisgarh, Madhya Pradesh, and Andhra Pradesh.

Coalfields in Jharkhand

Jharkhand accounts for about 29% of the coal reserves and 20% of coal production. Major Coalfields are Jharaia, Bokaro, Giridih, Karanpur, and Ramgarh, situated in rich coal deposit districts of Dumka, Dhanbad, Hazaribagh, and Palamu.

Major Coal Fields in Jharkhand
Jharia Coalfield

Jharia coal mine, situated in the Dhanbad district, is the largest coal-producing mine in India. It deposits the best metallurgical coal (Bituminous) and produced 90% of cooking coal. Bituminous coal from this field is also supplied to the iron and steel industries.

Bokaro Coalfield

It stretches in the valley of the Bokaro river in the district of Hazaribagh. The coal produced from this field is mainly supplied to the Bokaro iron and steel plant. Its Kargali seam is one of the thickest seams of the Gondwana Period.

Giridih (Karharbari) Coalfield

Giridih coalfield is situated in the Hazaribagh district. It provides the finest bituminous coal (coking coal) for metallurgical purposes. The coal produced is supplied to the Jamshedpur and Bokaro steel plants.

Karanpur and Ramgarh Coalfields

These coalfields are also situated in the district of Hazaribagh. The coal from these fields is of relatively inferior quality.

Hutar and Daltenganj Coalfields

Both the coalfields are present in the Palamau district. Coal produced is of Inferior quality, used in brick kilns & cement furnaces, but not for metallurgical purposes.

Deogarh Coalfields

Deogarh coal mine lies in the district of Dumka. The coal is of inferior quality, mainly used in Brick kilns.

Coalfields in Odisha

Odisha ranks second in coal reserves having more than 24% of total coal reserves and 15% of total coal production in the country. Most of the coalfields are found in the district of Dhenkanal, Sambalpur, and Sundargarh.

Talcher Coalfield

Talcher coal reserve is the second largest reserve in the country after Raniganj. It stretched from Talcher town to Rairkhol in Dhenkanal and Sambalpur districts. Its coal is of lower grade, suitable for steam and gas production, and mainly utilized in thermal power and fertilizer plants.

Rampur-Himgir Coalfields

RampurJimgir- coalfield lies in Sambalpur and Sundargarh districts, but the coal that occurs here is of inferior quality.

Coal Mines of Chhattisgarh

Chhattisgarh has the third-largest coal deposits (about 17%) in India and is one of the largest coal-producing states. Major coal deposits found are Kobra coalfield in Bilaspur districtJohilla coalfield in the Johillia valley, Jhimili coalfield in Shandol & Koriya districts, and Birampur, Hasdo-Arand, Lakhanpur, Sonhat & TataPani-Ramkota coalfield of Surguja district.

Coalfields in West Bengal

The first coal mine in India opened in 1774 in Raniganj district in West Bengal. About 11% of the total coal reserves of India are found in West Bengal, in the districts of Bardhaman, Darjeeling, Jalpaiguri, Bankura, and Puruliya.

Raniganj Coalfield

Ranijang is the important and largest mining coalfield in West Bengal. It is known for producing good quality coking coal. Its coal is mainly used in the Durgapur steel plant.

Coal Mines of Madhya Pradesh

Madhya Pradesh contributes around 8% of the total coal deposits of the country. Major coal fields are situated in Singrauli, Pench-Kanhan, Umaria, Muhpani, Satpura, and Saharanpur.

Singrauli Coalfield

Singrauli coalfield is the largest coal deposit in Madya Pradesh, stretched over the Sidhi and Shandol districts. Its Jhingurda coal seam is the thickest in the country. The other important coal seams are Panipahari, Khadia, Purewa, and Turra seams. Its coal is mainly utilized for the thermal power plant at Obra.
