What Type Of Plants Are Used In Coal Mining

Coal Types, Formation and Methods of Mining epcamr

Hydroponics is the use of nutrient containing water instead of soil in the growth of plant life. A third phase in this coal development is bituminous (soft coal) which is one of the two stages used as a fuel in generating electrical power. The fourth and final phase results in the formation of anthracite (hard coal).

What is coal used for? Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity.

Coal

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.
