Headquartered at Sambalpur in Odisha, it is engaged in the exploration, extraction and supply of coal from the Mahanadi valley coalfields, which are among the largest coal-producing belts in India.

Coal mining in the Mahanadi basin dates back to the colonial period, with the Ib Valley and Talcher fields being identified as significant reserves. After the nationalisation of coal mines in India in the early 1970s, these operations were brought under state control and later organised under Coal India Limited, formed in 1975. The mines in Odisha were initially managed by South Eastern Coalfields Limited (SECL) before being separated into a dedicated subsidiary.
Mahanadi Coalfields Limited was incorporated in 1992 as a separate subsidiary of Coal India Limited, carved out of SECL to focus on the rapidly expanding coal operations in Odisha. The company was created to give administrative and operational autonomy to the Odisha-based mines, given the scale of reserves in the Talcher and Ib Valley basins.
MCL's operations are organised across two major coalfield clusters in Odisha:
The company operates a mix of opencast and underground mines, with opencast mining accounting for the bulk of its production. Coal is dispatched through railway sidings, merry-go-round systems linked to pithead power stations, and by road.
MCL is one of the highest coal-producing subsidiaries within Coal India Limited and contributes significantly to India's domestic thermal coal output. Its production supports several major power utilities, including units of NTPC and various state electricity boards. The company also plays a substantial role in the economy of Odisha through royalties, employment, and infrastructure development in the mining belt, and undertakes corporate social responsibility activities in education, healthcare and rural development in its command areas.
As with other large opencast mining operations in India, MCL's activities have involved land acquisition, displacement of local communities, and concerns over air and water quality in the mining belts of Angul, Jharsuguda and Sundargarh. The company carries out rehabilitation and resettlement programmes, afforestation, and mine reclamation as part of its statutory and corporate obligations.
