Jharia coalfield

Meaning

Jharia coalfield is India's largest coalfield and its main source of coking coal. It lies in Dhanbad district, Jharkhand, in the Damodar valley. It matters for two reasons. It feeds India's steel industry. It is also famous for underground coal fires that have burned since about 1916, making the land sink and forcing people to move under the Jharia Master Plan.

Explanation

How the coal formed

• Gondwana coal: Jharia's coal is Gondwana coal. It formed about 200–250 million years ago in old river basins on the Peninsular plateau.
• Rift valley setting:
• The Damodar valley is a rift valley. This means a long strip of land sank down between faults (cracks in the earth's crust).

• Plant matter collected in this sunken land, was buried, and was preserved as thick coal seams (layers of coal).

• Damodar river: it starts in the Chota Nagpur plateau (the Palamu–Latehar area, Jharkhand). It flows east into West Bengal and joins the Hooghly. It was once called the "Sorrow of Bengal" because of its floods.

Why Jharia's coal matters: coking coal

• Coking coal is coal that turns into hard, porous coke when it is heated without air.
• Coke is needed to smelt iron ore (melt it to get iron) in a blast furnace.
• Jharia supplies the steel plants at Bokaro, Durgapur, Burnpur and Jamshedpur.
• Why steel plants sit near coal:
• Coal is bulky, and it loses weight when used because it burns to ash.
• Carrying it over long distances costs a lot.
• So it is cheaper to build steel and power plants close to the coalfield.

The Jharia fire: cause → process → result

• Cause: coal seams touch air through old mine workings.
• Process:
• The coal slowly oxidises (reacts with oxygen in the air) and heats up.
• In time it catches fire on its own.

• These underground fires have burned since about 1916.

• Result:

• The fire eats away the coal under the ground.
• The surface above cracks and sinks. This is called land subsidence.
• Homes in the fire and subsidence zones become unsafe, so people have to be moved.

Policy response: the Jharia Master Plan

• Jharia Master Plan: first approved in 2009. It moves people out of the fire and subsidence zones.
• Revised Jharia Master Plan: approved by the Cabinet Committee on Economic Affairs on 25 June 2025 [3].
• Total outlay is ₹5,940.47 crore [3].
• Fire, subsidence and rehabilitation (resettling people and helping them rebuild their lives) are handled phase by phase, starting with the most vulnerable sites [3].
• Each family gets a livelihood grant of ₹1 lakh and access to credit of up to ₹3 lakh. This covers both Legal Title Holder and Non-Legal Title Holder families [3].
• A Jharia Alternative Livelihoods Rehabilitation Fund will be set up. Roads, water, sewerage, schools and hospitals will be built at the resettlement sites [3].

Where it occurs

• Location: Dhanbad district, Jharkhand, in the Damodar valley coal belt (Jharkhand–West Bengal).
• Neighbouring Damodar fields: Bokaro, Giridih and Karanpura in Jharkhand, and Raniganj (Paschim Bardhaman district, West Bengal).
• Map order, roughly east to west: Raniganj → Jharia → Bokaro → Karanpura → Singrauli.
• State context: Jharkhand holds 87.84 billion tonnes of coal resource. That makes it second after Odisha (94.52 billion tonnes) and ahead of Chhattisgarh (80.77 billion tonnes), as on 1 April 2023 [2].
• Steel plants it feeds: Bokaro (Jharkhand), Jamshedpur (Jharkhand), Durgapur and Burnpur (West Bengal).

Don't confuse with

• Raniganj coalfield: it is in West Bengal and is the second largest and the oldest coalfield, mined since 1774. Jharia (Jharkhand) is the largest.
• Largest coal reserves (Odisha): Jharkhand has the largest single coalfield (Jharia), but Odisha has the largest reserves by state [2].
• Singrauli: it is called the "energy capital" because of its pithead power plants (power plants built right at the mine), such as NTPC Vindhyachal. Jharia is known for coking coal for steel, not for power.
• Tertiary coal: younger coal, about 15–60 million years old, found in the north-east. It is small in amount and has a lot of sulphur. Jharia's coal is older Gondwana coal.

Prelims Hooks

• Largest coalfield and main source of coking coal: Jharia, Dhanbad district, Jharkhand, in the Damodar valley.
• Fires: the underground fires at Jharia have burned since about 1916. They cause land subsidence.
• Revised Jharia Master Plan: approved by the CCEA on 25 June 2025, with an outlay of ₹5,940.47 crore [3]. The first plan was approved in 2009.
• Pair: Jharia – Jharkhand (largest). Raniganj – West Bengal (second largest, oldest, 1774).
• Trap: "Jharkhand has the largest coal reserves" is wrong. The order is Odisha > Jharkhand > Chhattisgarh (1 April 2023) [2].
• Steel link: Jharia's coking coal goes to Bokaro, Durgapur, Burnpur and Jamshedpur.

Mains Points

• Coal and industrial location (GS-I): coal is bulky and loses weight when used, so steel plants were pulled close to Jharia's coking coal. This built the Damodar industrial belt (Jamshedpur, Bokaro, Durgapur). It also put the costs of mining, such as pollution and displacement, on the people living there.
• Environmental and human cost (GS-III): century-old fires and subsidence have made settlements unsafe. The revised Master Plan of 2025 (₹5,940.47 crore) puts the most vulnerable sites first. It adds livelihood grants, credit access, an Alternative Livelihoods Rehabilitation Fund and basic services at resettlement sites [3]. Jharia shows that the true cost of coal is far higher than its market price.
• Regional planning and just transition: Jharkhand, Odisha and Chhattisgarh together hold close to 70 per cent of India's coal resource [2]. Jobs and state revenue in coal regions like Jharia depend on mining. So the shift towards the 500 GW non-fossil target for 2030 needs a fair plan for workers and families in these regions.
