CATEGORIZATION OF RESOURCES

The Coal resources of India are available in older Gondwana Formations of peninsular India and younger Tertiary formations of north-eastern region. Based on the results of Regional/Promotional Exploration, where the boreholes are normally placed 1-2 Km apart, the resources are classified into ‘Indicated’ or ‘Inferred’ category. Subsequent Detailed Exploration in selected blocks, where boreholes are less than 400 meter apart, upgrades the resources into more reliable ‘Proved/Measured’ category. The Formation-wise and Category-wise Coal resources of India as on 1.4.2018 are given in table below:
