Distribution of coal in India is largely confined to the eastern and central regions of the country. The biggest Gondwana coals resource belongs to 200 million years ago. They are mainly found in Jharkhand , West Bengal, Orissa, Chattisgarh as well as Madhya Pradesh states of India.
Gondwana Coal Fields:
Jharkhand: It has the largest share of the Indian coal deposit and also of production. There are some popular fields that include Jharia, Bokaro, and Raniganj.
-Odisha: Has Talcher coalfield which plays a crucial role in both, reserve as well as production.
-Chhattisgarh:It has Korba and Bilaspur, which have immense potential in depositing Coal and, it contributes to the extra ordinary Coal production in the country.
-West Bengal: The coal of Raniganj coal field contributes mais to the state as compared to other states although the latter have higher percentage contribution.
-Madhya Pradesh: It can be regarded as one of the principal suppliers of coal in the state.
Tertiary Coal Fields:
Secondary submature to mature coal deposits are less carbonaceous and are confined to the third order found in the northeastern region which comprises the Assam, Meghalaya, and Arunachal Pradesh states. These account for a lesser degree of India’s total coal output.
Lignite Coal:
Lignite is the brown coal that is mostly found in Neyveli coal fields of Tamil Nadu and holds a major share of lignite reserves of our country. Small deposits occur in Gujarat, Jammu and Kashmir, Kerala, Rajasthan, West Bengal and Puducherry.
Gondwana fields account for the largest portion of the countrys coal reserve concentration. Among them major states which have contributed include Jharkhand, Odisha and Chhattisgarh. It also has Tertiary coal and lignite however , the percentage of it is quite low.
The answer provides a general overview of the distribution of coal in India but lacks key data and important contextual information that would make the answer more comprehensive. It outlines the main coal-producing states and types of coal, which is good, but it misses some specific details and deeper insights. Here’s a more detailed evaluation:
Anita You can use this feedback also
Missing Facts and Data:
Quantitative Data: The answer does not mention specific statistics regarding the total coal reserves and production in India. For example, as of recent data, India has approximately 319 billion tonnes of coal reserves, with Gondwana coal fields accounting for the majority (about 98% of India’s total reserves).
Breakdown of Coal Types: While the answer mentions Gondwana, Tertiary, and Lignite coal, it could benefit from more detailed distinctions between the qualities of these coals (e.g., low to high calorific value) and their significance for energy production.
Tertiary Coal Fields: The answer should specify that the Tertiary coal fields in the northeastern region, such as in Assam, Meghalaya, and Arunachal Pradesh, are primarily of a lower grade, and thus, less significant for power generation.
Other States: It misses some other important coal-bearing states such as Telangana and Andhra Pradesh, where significant deposits are found, especially in the Singareni coalfields.
