 · Coal is that sooty black stuff one usually associates with the late 1800s and Santa Claus.But coal, a fossil fuel, is the largest source of energy for the generation of electricity worldwide, as well as one of the largest worldwide anthropogenic sources of global warming.Gross carbon dioxide emissions worldwide from coal usage are slightly more than those from petroleum and about double …


Coal is a carbon-containing rock formed by the debris from the decay of ferns, vines, trees and other plants which flourished in swamps millions of years ago. Over time, the debris became buried and the actions of bacteria, heat and pressure transformed the debris first into peat (a precursor of coal) and then into the various types of coal as we know them today.

Century contract

In 1945 coal production fell from 130.2 million tons (1939) to 33.4 million tons. The consequence was a great shortage on the market, this "coal shortage" was the beginning of the small-scale mining . In 1947, the German Coal Mining Management (DKBL) was founded to direct the production of hard coal and lignite mining.

Coal Mining in Uinta Basin

The 1970''s boom in Utah coal mining also drove a boom in coal-fired power plant construction. Out of Utah''s 5,080 MW of coal-fired generating capacity, 93% comes from plants built since 1974 – unusual in the U.S., where the median coal plant was built in 1964. Read more about Utah coal mining and the Uinta Basin at CoalSwarm.


In the United States coal rank is classified according to its heating value, its fixed carbon and volatile matter content and, to some extent, its caking characteristics during combustion. Anthracite: Used primarily for residential and commercial space heating, anthracite is the highest rank of coal.

Water pollution from coal

Water Pollution from Coal includes negative health and environmental effects from the mining, processing, burning, and waste storage of coal, including acid mine drainage, thermal pollution from coal plants, acid rain, and contamination of groundwater, streams, rivers, and seas from heavy metals, mercury, and other toxins and pollutants found in coal ash, coal sludge, and coal waste.

Coal mining

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine …

coal mines website template

After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, increasing the heating value of the coal. During this coal processing, the used industrial equipment can be called coal processing equipments.

Coal and jobs in the United States

 · In September 2011, the National Mining Association issued a press release stating that potentially 1.24 million jobs in 36 states had been destroyed by the Sierra Club''s "Beyond Coal" campaign aimed at stopping construction of new coal-based power plants. The number was based on NMA projections of jobs that would have been created had the plants come online.

Carbon Dioxide Emission Factors for Coal

Carbon Dioxide Emission Factors by Coal Rank and State of Origin. The (arithmetic) average emission factors obtained from the individual samples (assuming complete combustion) (Table FE4) (10) confirm the long-recognized finding that anthracite emits the largest amount of carbon dioxide per million Btu, followed by lignite, subbituminous coal, and bituminous coal.

Coal mining

 · Mining has always been dangerous, because of explosions, cave-ins, methane gas and the difficulties of timely underground rescue. The worst single disaster in British coal mining history was at Senghenydd in South Wales. On the morning of 14 October 1913 an explosion and subsequent fire killed 436 men and boys. Only 72 bodies were recovered.
