Coal Mines In India 2026, State Wise List, Top 10, Underground Mines

Coal Mining refers to the extraction of coal deposits from both the Earth’s surface and underground layers. Coal played a crucial role as the primary source of energy during the Industrial Revolution, driving industrial expansion and leading to large-scale exploitation of coal reserves. By the late 20th century, open-pit mining gradually replaced underground mining as the dominant method in many industrial nations. With advancements in technology, Coal Mines In India 2026 today whether surface or underground has become a highly mechanized and efficient process. In India, the first coalfield was discovered at Raniganj, where mining began in 1774 under the East India Company. Owing to its vast reserves of ancient hard rocks, India holds significant mineral resources, with coal continuing to be one of its most important.

Coal Mines in India 2026

India holds significant coal reserves of around 400.715 billion tonnes, making it one of the largest coal producers in the world. The major coal-bearing areas are concentrated in the eastern and central regions of the country. The dominant types of coal found in India are bituminous and sub-bituminous, which are widely used for power generation and industrial purposes.

Coal Mines in India are broadly classified into two categories – Gondwana Coal and Tertiary Coal.

• Gondwana Coal, among the oldest and most important reserves globally, is mainly located in central India. It forms the bulk of India’s coal resources.
• Tertiary Coal, comparatively younger in age, is primarily found in the northeastern states, such as Meghalaya, Assam, and Arunachal Pradesh.

Within the Gondwana Reserves, coal is further categorized based on its carbon content into anthracite, bituminous, and sub-bituminous varieties. These categories determine the energy content and suitability of coal for different applications, ranging from domestic use to large-scale power generation and industrial consumption.

Coal Reserves in India 2026

The National Coal Inventory of 2025 Report published by Geological Survey of India estimates the total Coal Resources in India to be 400.715 billion tonnes as of April 2025. As of 2026, 64 Coal Fields are operational which include 45 Gondwana and 19 Tertiary Coalfields. In addition, country has a total 15 Lignite Fields which reserves 47.37 billion tonnes of Lignite Resources (2025).

List of Coal Mines in India 2026

In India, there are several places where coal is mined from the ground. These areas are called coal mines, and they are mainly located in states rich in mineral resources. Some of the famous Coal Mines in India include:

What are the Types of Coal?

Coal in India is classified into four main types based on its carbon content, heating capacity, and age. These types range from the oldest and most energy-rich (Anthracite) to the youngest and least carbon-rich (Lignite). Each type has distinct properties and uses, and their distribution varies across regions.

Kusmunda Open Cast Mine is the second largest coal mine in India. In FY 2023-24, it produced more than 50 million tonnes of coal. Along with Gevra Mine, it also uses advanced and environment friendly mining machines such as Surface Miner which extract and cut coal without blast.

3. Dipka Open Cast Project (Chhattisgarh)

Dipka Open Cast Project is a flagship mega mine under SECL. On an average, it produces more than 35 million tonnes of Coal per year and has targeted more than 40 million production in the FY 2026-27. 

4. Jharia Coalfield (Jharkhand)

The Jharia Coalfield is located in the Dhanbad district of Jharkhand, popularly known as the “Coal Capital of India”. It is famous for producing high quality metallurgical (coking) coal. It has the Largest Coal Reserve in India 2026 estimating to about 19.4 billion tonnes.

5. Raniganj Coalfield (West Bengal & Jharkhand)

Raniganj Coalfield is the oldest and the second largest coal mining region in West Bengal. The mine was set up and began it’s operations in 1774. It produces high grade non-coking coal.

6. Talcher Coalfield (Odisha)

The Talcher Coalfield is one of the largest coal mines in India. It estimates the reserves of about 15% of the total prognosticated coal resources in India. It is operated by Mahanadi Coalfield. In FY 2022-23, it produced more than 95 million tonnes of Coal and is projected to produce about 300 million tonnes till 2030.

7. Singrauli Coalfield (Madhya Pradesh & Uttar Pradesh)

Singrauli Coalfield is operated by Northern Coalfields Limited (NCL). In FY 2025-26, it has achieved the annual target of producing 140 million tonnes of coal. It is popularly known as the “Energy Capital of India”. It supports two mega mines Jayant and Nigahi that are useful in thermal power generation.

8. Bhubaneswari Open Cast Mine (Odisha)

The Bhubaneswari Open Cast Mine is located in the Angul district of Odisha. It is operated by Mahanadi Coalfields Limited (MCL). The mine has the capacity of producing 30 million tonnes coal. 

9. Ib Valley Coalfield (Odisha)

Oldest Coal Mines in India 2026

Coal Mining in India has a long history, with some mines operating for more than a century. These mines not only powered industries during the colonial period but also laid the foundation for India’s modern energy sector. Here are two of the Oldest Coal Mines in India:

Underground Coal Mines in India 2026

In India, along with the Open Cast Mines several Underground Mines are also operational. These mines are generally used for extraction of deep-seated coal seams which are typically located above 200 feet of depth. The major examples of Underground Coal Mines in India include:

• Jhanjra Mines: It is located in West Bengal. The Jhanjra Mine is the largest highly mechanized underground coal mining project in India. It is operated by Eastern Coalfields Limited and is extended upto 225m of depth below surface.
• Churcha Mine: It is located in the Koriya district of Chhattisgarh and is operated by South Eastern Coalfields Limited (SECL). It has the average capacity of 2.10 million tonnes of coal production.
• Adasa Mine: The coal mine earlier operated as the underground coal mine under Western Coalfields Limited (WCL). However, in 2019 it officially concluded it underground works and reopened in 2020 as an opencast mine. Thus as of 2026 it is no more an underground coal mine of India.
