This lists of mines in India is subsidiary to the list of mines article, and future mines in the country and is organised by the primary mineral output. For practical purposes stone, marbles and other quarries may be included in this list. In India, the underground mine to surface mine ratio is 20:80 [citation needed].
Coal in India has been mined since 1774, and India is the second largest producer and consumer of coal after China, mining 997 million metric tons (1,099 million short tons) in FY 2023-24. Around 20% of coal is imported.
The mining activities in these coalfields started in 1894 and had really intensified in 1925.

[7] Production from open cast mines during FY 2014–15 was 92.91% of total production of 494.24 MT. [7] Underground mines contributed to 7.09% of production.
The volatile matter ranges from 25-30 per cent. The calorific value of the coal varies from 4,200-5,900 Kcal/kg. [2] Almost all of India’s coal reserves are of Gondwana coal. Thickness of coal seams in Indian coalfields generally range from 1 m to 30 m. An exceptionally thick seam of 138 m has been discovered in Singrauli coalfield. [3]
According to Geological Survey of India, reserves of coal as on 1.1.2004 in Rajmahal Coalfield were 13.13 billion tonnes. It was the third highest reserve in Jharkhand, after Jharia Coalfield (19.4 billion tonnes) and North Karanpura Coalfield (14.6 billion tonnes).
