If we talk about the production amount of a coal mine in India, sure, Gevra mine is at the top of the list, but just one spot down, there is Kusmunda Opencast Mine, which is again, situated in the Korba district of Chhattisgarh. Yes, that much coal is found in this state, so no wonder there are so many popular coal mines. Talking about the production amount, well, it is not very far off from the Gevra. To be precise, it is actually 50 million tonnes per annum (MTPA) capacity. These first two are the biggest coal mines, not just in India, but they have made it to the top 5 coal mines in the world’s list too [1].
The mine’s normative production capacity is 50 million tonnes per year (Mtpa), with a peak capacity of up to 62.5 Mtpa. In the 2023-24 fiscal year, Kusmunda produced over 50 million tonnes of coal, making it only the second mine in India after Gevra to surpass this mark.
The mine covers more than 18.5 square kilometers, and recent estimates highlight coal reserves of over 1.1 billion tonnes. Expansion plans would increase the total land area to over 3,510 hectares.
