Question

Describe the production and distribution of coal in India.

Hint:

Quote the big belts: Damodar (Jharia–Raniganj), Mahanadi (Talcher–Ib), Singrauli–Korba, Wardha–Singareni; add Neyveli lignite. Mention CIL/SCCL, opencast dominance, and high ash to round off.

Answer 1

Importance and types
Coal is India's dominant commercial fuel for electricity, steel (coke), cement and industry. Indian coals are mainly Gondwana (Permian; coking and non-coking) found in peninsular river valleys, and Tertiary coals in the North-East. Lignite (brown coal) occurs in younger sedimentary basins.
Production—general features
Most output comes from opencast mines (high productivity); underground mining is limited. Public sector companies, especially Coal India Ltd. (CIL) and its subsidiaries, dominate production alongside Singareni Collieries (Telangana). Power utilities consume the bulk; coking-coal quality limits require imports for steel blending. Indian coals are often high ash (affecting efficiency) and need beneficiation.
Spatial distribution by coalfields / states
1) Damodar Valley (Jharkhand–West Bengal):
\hspace*{0.5cm}Jharia (prime coking coal; but fire/subsidence issues), Raniganj, Bokaro, Karanpura, Giridih. These fields underpin eastern steel plants and coke ovens.
2) Mahanadi Valley (Odisha):
\hspace*{0.5cm}Talcher and Ib Valley (major thermal coal belts) support coastal power and industry; proximity to Paradip/Dhamra ports aids logistics.
3) Son–Mahanadi–Narmada (MP–Chhattisgarh–UP):
\hspace*{0.5cm}Singrauli (Madhya Pradesh–Uttar Pradesh) fuels super thermal power; Korba and Hasdeo–Arand (Chhattisgarh) are large opencast hubs; Sohagpur and East/West Kanhan occur in MP.
4) Wardha–Godavari Valley (Maharashtra–Telangana):
\hspace*{0.5cm}Wardha Valley (Maharashtra: Chandrapur, Yavatmal, Nagpur) and Godavari Valley / Singareni (Telangana: Bhadradri–Kothagudem, Mancherial) supply western and southern grids.
5) Pench–Kanhan–Tawa / Satpura (MP–Maharashtra):
\hspace*{0.5cm}Mines around Chhindwara, Betul, Shahdol feed regional power and industry.
6) North-Eastern Tertiary coals (Assam–Meghalaya–Arunachal–Nagaland):
\hspace*{0.5cm}Makum (Assam), Garo–Jaintia–Khasi (Meghalaya), Namchik–Namphuk (Arunachal) and Mon–Tuensang (Nagaland). Higher volatile content; scattered, often small deposits.
7) Lignite belts (younger deposits):
\hspace*{0.5cm}Neyveli (Tamil Nadu) is India's flagship lignite field (pithead power, chemicals). Other lignite areas: Rajasthan (Barmer, Bikaner, Nagaur), Gujarat (Kachchh, Surat), and pockets in J&K.
State-wise snapshot to write in exams
Jharkhand and West Bengal: coking and non-coking in Damodar valley (Jharia, Raniganj).
Odisha: Talcher–Ib thermal coal; integrated with iron–steel and power.
Chhattisgarh: Korba, Hasdeo–Arand; large pithead power.
Madhya Pradesh–Uttar Pradesh: Singrauli super thermal hub; Satpura fields.
Telangana: Singareni (Godavari valley) under SCCL.
Maharashtra: Wardha valley (Chandrapur–Wani) fuels western grid.
Assam–Meghalaya–Arunachal–Nagaland: smaller, Tertiary coals.
Tamil Nadu–Rajasthan–Gujarat: lignite-based power (Neyveli; Barmer etc.).
Factors explaining patterns
Gondwana basins along ancient river valleys (Damodar, Son, Mahanadi, Godavari) host most reserves; proximity to steel plants, power stations, railways and ports shapes current output. Policy (block auctions, environment–forest clearances), mechanisation, and evacuation capacity (rail sidings, merry-go-rounds) drive growth.
Constraints and responses
High ash content, land acquisition, mine fires (Jharia), environmental rehabilitation, rail evacuation bottlenecks, and rising quality needs of steel. Responses include beneficiation, washeries, first-mile connectivity, overburden management, and reclamation with afforestation and water bodies.
