(Of course, on a tonnage basis, lower grade coals do produce more carbon dioxide than higher grade coals.) Domestic coal in India is typically sub-bituminous (heat rate 4,200 kcal/kg or 7,560 Btu/lb), while imported coal is typically bituminous (6,665 kcal/kg or 11,997 Btu/lb).

Types of coal found in India. Anthracite: It is the highest grade of coal containing a high percentage of fixed carbon. It is hard, brittle, black and lustrous.

of coal formation, a carbon-rich material called peat was formed. In the subsequent geochemical stage, the different time-temperature histories led to the formation of coals of widely differing properties, as summarized in Table 7-1 and discussed below. TABLE 7-1 Carbon content and age of different coals Coal type Approximate age (years ...

The term coal quality is used to distinguish the range of different commercial steam coals that are produced directly by mining or are produced by coal cleaning. 3 Generally, coal quality for steam coals (i.e., coal used for electricity generation) refers to differences in heating value and sulfur content, although other characteristics such ...

World over large reserves of low grade coals are available. The use of low-grade coal in various industries like power plants, metallurgical plants, cement units, etc. creates environmental pollution because of generation of large amount of solid and gaseous pollutants.

The Global Coal Mine Tracker uses the 0.017 exclusion factor (1.7%) for all coal types, since emissions from coking coal should still be counted in general inventories. When GCMT data is used for a general compilation, it uses 0.017, but when the compilation is relevant to power sector only, it includes 0.645 for coking coal.

Coal mine workers have to carry out mining activities then. Disadvantages of Coal. Coal has a set of disadvantages: like coal mining accidents, coal pollution, etc. There are a large number of accidents that take place in coal mines because it is a dangerous and challenging activity involving heavy equipment.

for imported coal comes out approximately as Rs0.66 (1US$=Rs41) for domestic coal and Rs1.57 for imported coal. Since, the grades camouflage the hidden ash range, the under-pricing appears to be a direct fall out of the current pricing system. It also seems to be in our mind set that Indian coals, because of their high ash, cannot be priced high.

It dismissed the coal-stock shortage and emphasised that various stakeholders involved in the chain, such as Coal India Limited (CIL) and railways, are closely monitoring the situation.
