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’ category. The Formation-wise and Category-wise coal resources of India as on 1.4.2012 are given in table below:
