Coal & Lignite Resource

According to the National Coal Inventory of 2023, published by Geological Survey of India based on resources estimated by CMPDI, GSI, MECL, SCCL, and some private/public entrepreneurs, a maximum depth of up to 1200m.; the total estimated coal reserve (resource) of India is 378.21billion tonnes as of 01.04.2023.

With Continuous exploration efforts in 64 coal fields (45 Gondwana &19 Tertiary Coalfields) and 15 lignite fields have resulted in substantial augmentation of the geological resources of coal and lignite.As 1st April’2023 total updated geological coal and lignite resources of the country stand at 378.21 billion tonnes and 47.36 billion tonnes respectively. An amount of 16.8billion tonnes of coal and 1.16 billion tonnes of lignite resources have been augmented in the year 2022-23

                                                                                                                         (Billion tonnes)

Lignite Resource

The inventory of lignite resources for the year 2022-23 was prepared by compiling and collating updated information from different lignite exploration agencies, such as NLC India Ltd., Geological Survey of India (GSI), and Mineral Exploration Corporation Limited (MECL). The finalization of the inventory was done through close interaction between GSI and NLC. As of 1st April 2023, the total geological resource of lignite in the country stands at 47.36billion tonnes.
