Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Under the Phase II, Alternative Energy Resources Development (AERD) project of the United States Agency for International Development (USAID) and the Government of India (GOI), five collaborative coal projects have been initiated in the areas of: (1) NO{sub x}/SO{sub x} control from coalfired power plants, (2) slagging combustor development for highash Indian coals, (3) characterization of ...
Aiming at the problem of coal gangue identification in the current fully mechanized mining face and coal washing, this article proposed a convolution neural network (CNN) coal and rock identification method based on hyperspectral data. First, coal and rock spectrum data were collected by a nearinfrared spectrometer, and then four methods were used to filter 120 sets of collected data: first ...
India has the fourth largest reserves of coal in the world. Indian coal reserves as per the latest estimate of Geological Survey of India, including coal and lignite up to a depth of 1200 m, are 327 Billion tonne (Bt) (GSI, 2011), out of which coal is 286 Bt and lignite 41 Bt in two important geological horizons of Permian (250300 million years) and Tertiary Periods (65180 million years).

China accounted for approximately % of the world's total coal consumption in 2019, and India at %. The largest coal reserves in the world are in the USA, Russia, China, Australia and India. ...
The cost of energy per unit at pithead for domestic coal and at port for imported coal comes out approximately as (1US=Rs41) for domestic coal and for imported coal. Since, the grades camouflage the hidden ash range, the underpricing appears to be a direct fall out of the current pricing system. It also seems to be in
The Coal Ministry Friday announced that the government has fixed a target of billion tonnes (BT) of coal production for FY 202425, adding that the same will go up to BT by FY30. This comes as India's domestic coal production has increased by over 16 per cent in the current financial year as energy demand continues to rise.

The coal crisis in the country has hit the textile processing units in Surat hard. Nearly 400 units in this southern Gujarat city, employing close to 500,000 people, plan to cut down production from next month because of rising coal prices. Industry executives said an increase of nearly 50% in costs of colour and other chemicals in the past two months has added to the woes of textile processors.
Demand for a cleaner source of energy is increasing in India. In the search for alternate energy sources, coal bed methane gas receives considerable attention for its potential as a good energy source. During the coalification process, methane gas is captured in the coal seams and later released during coal mining operations. Coal bed methane separation is crucial for both economic benefit and ...
How coal is formed. Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, lowcarbon peat, to coal, an energy and carbondense black or brownishblack sedimentary rock.
According to the annual census of coal preparation plants conducted by Coal Age [], the USA operates 286 coal preparation plants in 12 number is relatively small by comparison to the worldwide fleet which is estimated to be 2,283 plants [].The capacity of the plants can range from less than 200 t/h for small operations to 6,000 t/h or more for large industrial plants.
The shortage in coal is a result of a sharp uptick in power demand as the economy recovered from the effects of the pandemic. Total power demand in August was 124 billion units up from 106 billion units in August 2019. A sharp increase in the international prices of coal due to a shortage in China and low accumulation of stock by thermal power plants in the AprilJune period have also ...
India has the thirdlargest coal resource after China and United States, where about 67% of the total energy consumption is from the coal sector.
