Mar 01, 1984 · Physical processes disintegrate the coal to increase the reactive surface area of the grains and make oxygen penetration into the bed easier. The processes that produce physical deterioration of the coal are most active in the outer 50 cm of the outcrop, and thus, this zone also shows the most intense chemical weathering (Figure 2).

The price for any particular coal is related directly to coal quality (Box 4.1 and Table 4.2). Because more than 90 percent of the coal mined in the United States is used in power plants to generate electricity using steam turbines, the price for steam coal is dependent primarily on its .

What is Coal? Coal is an organic sedimentary rock that forms from the accumulation and preservation of plant materials, usually in a swamp environment. Coal is a combustible rock and, along with oil and natural gas, it is one of the three most important fossil fuels.Coal has a wide range of uses; the most important use is for the generation of electricity.

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is 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.
