Bituminous Coal, Features, Distribution, Production, Initiatives

Bituminous Coal is a widely available fossil fuel commonly called Black Coal due to its dark colour and high carbon content. It contains a tar like substance called bitumen. It is formed through geological coalification processes at temperatures above 85° C. It is globally abundant and widely used for electricity generation, steel manufacturing and industrial fuel due to its high calorific value and strong carbon concentration.

Bituminous Coal Features

Bituminous Coal is a dense fossil fuel with high carbon concentration and significant energy potential. The major features of the coal has been listed below:

• Carbon Content: Bituminous Coal generally contains about 40-80% carbon, while detailed chemical composition averages nearly 84.4% carbon, 5.4% hydrogen, 6.7% oxygen, 1.7% nitrogen and 1.8% sulfur by weight.
• Physical Property: This coal type appears dark brown to deep black and is dense yet friable. Coal seams usually show alternating bright and dull bands formed during organic deposition.
• Bitumen: The name “bituminous” originates from bitumen, a sticky tar like substance present in the coal that softens and swells when heated.
• Combustion Behaviour: During burning, it usually produces a smoky flame and softens before forming coke like porous residue due to the bitumen content.
• Geological Formation: It forms when sub-Bituminous Coal is buried deeper underground and exposed to temperatures above 85°C during coalification.
• Industrial Uses: Bituminous Coal is widely used in thermal power plants, steel production through coke manufacture and production of activated carbon.

Bituminous Coal in India

Bituminous Coal plays a central role in India’s energy system, industrial development and electricity production infrastructure.

Distribution

Bituminous Coal deposits in India are concentrated mainly in eastern and central regions within major Gondwana coalfields.

• States: Significant reserves occur in Jharkhand, Odisha, Chhattisgarh, West Bengal and Madhya Pradesh, mainly across Damodar Valley (Jharia, Raniganj), Mahanadi Valley (Talcher), Son Valley, etc.
• Largest Reserves: Jharkhand holds the highest coal reserves in India, followed by Odisha, Chhattisgarh, West Bengal and Madhya Pradesh.

Production

• Total coal production in India reached about 730.354 million tonnes in 2018-19, showing nearly 7.9% annual growth.
• Coal accounts for roughly 55% of India’s total energy requirements, making it the most important fossil fuel in the country.

Challenges

• India imports nearly 213 million tonnes of coal annually, mainly high quality coking coal required for steel manufacturing.
• Coal mining expansion frequently encounters land acquisition disputes and rehabilitation challenges.
• Strict environmental regulations increase operating and maintenance coal mines.
• Growing electricity demand after power sector reforms in 2003 created supply shortages in domestic coal production.

Government Initiatives

• Coal Mines Nationalisation Act 1973: This legislation brought most coal mines under government control and established centralised sector management.
• Commercial Mining Reform: Private and foreign companies were allowed to participate in commercial coal mining to increase competition and efficiency.
• Coal Mines Special Provisions Act 2015: This law introduced transparent auction based allocation of coal blocks after earlier allocations were cancelled.
• UTTAM Monitoring App: The Ministry of Coal launched the UTTAM mobile application in 2018 for third party assessment and transparency in coal quality monitoring.
