Coal National Geographic Society

Dec 22, 2012· Coal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity.It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the United States.

Brown coal coal classification Britannica

Brown coal, broad and variable group of low-rank coals characterized by their brownish coloration and high (greater than 50 percent) moisture content. These coals typically include lignite and some subbituminous coals.In Great Britain and other countries, the term brown coal is used to describe those low-rank coals (lignite and subbituminous coal) that generally have a brown colour.

Refined coal Wikipedia

Refined coal is the product of the application of a coal-upgrading technology that removes moisture and certain pollutants from lower-rank coals such as sub-bituminous and lignite (brown) coals and raising their calorific values. Coal refining or upgrading technologies are typically pre-combustion treatments and/or processes that alter the characteristics of a coal before it is burned.

Alternate uses for brown coal Earth Resources

Brown coal is not currently widely traded due to the challenges in exporting the raw resource. 'Run of mine' brown coal from Victoria's reserves in the Latrobe Valley is reactive and has a high moisture content, which makes it unsafe and uneconomic to export without processing (drying and stabilising). Other opportunities for brown coal

Coal Wikipedia

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.

Coal Production an overview ScienceDirect Topics

Coal production continues to grow globally due to the demand for low cost energy and iron and steel, as well as cement. Coal, based on the current extraction rates, will last about 115 years longer than conventional oil and gas reserves, with an estimated 1.1 trillion tonnes of proven coal reserves worldwide. Ten countries are responsible for 90% of the total global coal production.

Opencast Mining an overview ScienceDirect Topics

In surface mining, all of the rock from the ground surface to the top of the seam (material referred to as overburden) is removed and set aside to expose the coal, which is then taken out and transported from the mine for preparation and use (Figure 11). With underground mining, in contrast, a series of openings is made from the surface to the
