temporal and spatial distribution of coal in india

coal distribution of major states and major coal fields in India,different charrecteristics of Gondwana and Tertiary coals in India

1. TEMPORAL AND SPATIAL DISTRIBUTION OF COAL IN INDIA SOUMYARANJAN SAHOO

2. TEMPORAL DISTRIBUTION Gondwana coal Tertiary coal(15-60my) Most of coals are from karaharbari, Barakar ,& Raniganj formations.

3. CHARECTERISTICS OF GONDWANA COAL In I ndia about 98% of coal produced from G ondwana coal fields & coal seams are associated with sandstones. Most of the G ondwana coals are of bituminous type. Mostly black in colour &carbon is more than 70 %. In I ndia 80 out of 113 coal fields are of G ondwana coal. Almost free from moisture and contains small amount of sulphur . Volatile and ash content is about 13-30%. Most of them are noncoking (except jharia,bokaro,giridh ).

4. CHARECTERISTICS OF TERTIARY COAL In I ndia about only 2% of coal are produced from tertiary coal fields & these are of lignite type. Very low carbon(30-50%) & brown in colour . High sulphur contain & very less amount of gold . Coal seams of NE are highly folded hence difficult to mine. Coal seams are associated with limestone & slates. 90% of the tertiary coal are in Ney valley.

5. SPATIAL DISTRIBUTION OF COAL Distribution of G ondwana coal. Gondwana coals in India are found in river valleys. 1.Damodar valley(West bengle and Bihar) 2.Son-Mahanadi valley(M.P &Odisha) 3.Wardha-Godavari valley(A.P & Maharastra )

6. STATE COAL FIELDS West Bengal Raniganj,Bankura Bihar Jharia,Giridih,Bokaro,Daltonganj,Karanpur,Ramgarh Odisha Talchir,Rampur-Hingir ( Sambalpur District) Andhra Pradesh Singareni,Kamavaram M.P Umaria,Singrauli,Korba,Chirmiri,Sohagpur , Bisrampur,Mohapani Maharastra Kota,Chikiyala,Rajur,Bandar Gujurat Ghunkeri IMPORTANT COAL FIELDS OF GONDWANA Lower G ondwana Lower & upper Gondwana Upper Gondwana

7. IMPORTANT COAL FIELDS OF TERTIARY STATE COAL FIELDS Assam Umasor,Charogaon,Jarain , karaibari,Tura,Sogring Jammu & Kashmir Ladda,Kalkoth,Methkha Rajasthan Palana (in Bikanir ) Tamil Nadu Neyvalley,Cuddalore Kerala Varkala,Quilon Gujurat Umarsar (in kutch ) Khasi & jaintia hills Garo hills
