Learning Geology: Coal
· Coal is a flammable black hard rock used as a solid fossil fuel. It is mainly made up of 6595% carbon and also contains hydrogen, sulphur, oxygen and nitrogen. It is a sedimentary rock formed from peat, by the pressure of rocks laid down later on top. The harder forms of coal, such as anthracite, are metamorphic rocks because they were changed ...

Coal Rank, Kentucky Geological Survey, University of Kentucky
· Coal Rank. The stages of physical and chemical changes that proceed from peat through coal are called coalifiion, and are classified and described by rank. In general, rank egories are defined based on recognizable changes in coal parameters. Slightly different egories and parameters are used in different countries, but in general ...

Germany's three lignite mining regions | Clean Energy Wire
Germany has been the largest lignite producer in the world since the beginning of industrial lignite mining. It still is, followed by China, Russia, and the United States. The softer and moister lignite (also called brown or soft coal) has a lower calorific value than hard coal and can only be mined in opencast operations. When burned, it is more CO2 intensive than hard coal.
