Gondwana basins of Peninsular India disposed in four linear belts following several prominent lineaments in the Precambrian craton. In the extra-Peninsular region (Darjeeling and Arunachal Pradesh) Lower Gondwana sediments occur as thrust sheets overriding Siwalik sediments.
Gondwana coal Occurrence
Eastern and central part of Peninsular India
Rank Character
Bituminous to sub-bituminous Moderate to High in Ash and Low in Sulphur
Tertiary coal Occurrence Rank Character
Northeastern India Meta and Ortholignitous High in Sulphur ; Strongly caking to non-caking
Lignite Occurrence Character
Western and southern India High in Moisture and Volatile Matter
GONDWANA COAL Coal bearing strata
RANIGANJ/KAMTHI FORMATION (Late Permian)– ECONOMICALLY EXPLOITABLE IN RANIGANJ, JHARIA EASTERN PART OF SINGRAULI BASIN AND GODAVARI
BARAKAR FORMATION (Early Permian)– MAJOR STOREHOUSE OF COAL IN ALL THE BASINS
KARHARBARI FORMATION (Early Permian)– RESTRICTED TO FEW COALFIELDS OF EASTERN INDIA
TERTIARY COAL Coal bearing strata Oligocene sediments – Tikak Parbat Formation in Upper Assam, Nagaland and Arunachal Pradesh Eocene sediments – Tura Sandstone, Lakadong Sandstone in Garo, Khasi and Jaintia hills of Meghalaya Sylhet Limestone in Mikir hills of Assam Lower Subathu Group in Jammu
Coking
Types of Indian coal
Prime – Low volatile bituminous coals , Coke type G7 or better, Ro(mean) = 1.2.
Upper Barakar seams in Jharia coalfield.
Medium - Low to high volatile bituminous coals, Coke type FG6, Ro(mean) = 1.1-1.4. Lower Barakar & Raniganj seams in Jharia, Barakar seams in Raniganj, Bokaro, parts of Ramgarh, Karanpura, Sohagpur and Pench- Kanhan coalfields
Semi – High volatile, Coke type D-F, Ro(mean) = 0.7. Lower Raniganj seams in Raniganj, Barakar seams in parts of Ramgarh and Sonhat coalfields
Non-coking
Superior – High volatile bituminous B-C coals. Mainly in Raniganj seams of Raniganj coalfield
Inferior – High volatile sub-bituminous coals. High Sulphur
All coalfields
Tertiary coalfields of Northeastern Region
General characters of Karharbari coal
Comparatively cleaner than Barakar coals Low moisture, low ash and low to medium volatile Generally non-coking except in parts of Giridih and North Karanpura
General characters of Barakar coal Moisture < 2% to 6% Volatile - <18 to 35% Carbon - 85 to 90% (on dmf basis) Ash - 15 to 30% (excluding dirt bands) Coking properties (eastern CFs of Damodar Valley basins) Coke type - D to G6 or better
General characters of Raniganj coal High moisture High Volatile Coal seams thinner than those of Barakar Best developed in Raniganj coalfield
