The coal seam classification obtained from this HCA model is shown in Table 7. The coal seams of all three classes are occurring at a depth of more than 500 m and are having thickness of more than 1 m which are primarily required for planning of any CBM project.
Sep 01, 2013 The moisture content is representative of the inherent moisture of the coal which ranges from 0.7 to 1.2. Moisture content in all seams of the study area is generally below 2 and therefore, these seams contain low moisture coal as per Indian classification . All core samples have medium to high volatile matter content ranging from 15.4 ...

2.1.2 Indian Cnal Quality The coal quality of different coal fi elds from India is given in Table 2ref. 15. India has 70 bt reserve of coal amounting to almost 7 per cent of the global reserves. Significantly, 86.4 per cent of coal reserves in India lie within easil y exploitable depth of 600 m. The Indian coal
blasting, these bands intermix with coal as a result quality is further deteriorated. Thinner coal seams are not workable in present conventional system of coal mining as a result non-renewable source of energy is wasted. Introduction of surface miner in Indian opencast coal

Note 1 to entry In the geological coalification sequence, the transformation from peat to coal is defined as occurring when the total in-situ moisture content has decreased to 75 by mass. The upper limit for undisturbed coal seams in the normal coalification process leading to semi-graphite is defined as corresponding to a mean random vitrinite reflectance, , of 6,0 or, preferably, a mean ...
The Indian coal sector Challenges and future outlook 9 Steel sector Coal is an essential input in the production of steel. In 2011, the world crude steel production reached 1,518 MT, reflecting a growth of 6.2 over 2010. The per capita finished steel consumption in 2011 is estimated at 215 kg for world and 460 kg for China, ...

Jan 26, 2016 Gondwana coal forms Indias metallurgical grade as well as superior quality coal. The Damuda series i.e. Lower Gondwana possesses the best worked coalfields accounting for 80 per cent of the total coal production in India. 80 out of 113 Indian coalfields are located in the rock systems of the Damuda series lower Gondwana Age .
Coal deposits in India are of two distinct geological ages. The earliest coal deposits are of Permian age formed about 270 million years ago. At that time South Africa , South America , Antarctica , Australia , India and Madagascar formed a landmass called Gondwanaland. Coal formed in Gondwanaland are known as Gondwana Coal .
