In order to use coal as an energy source, the coal needed to be mined. Mining has always been a difficult and dangerous profession. Watch the videos and then follow the links below to learn about the different types of mining used to "harvest" coal and to learn a little about the history of coal mining.

Coal is a combustible black or brownish-black sedimentary rock with a high amount of carbon and hydrocarbons. Coal is classified into four main types, or ranks depending on the types and amounts of carbon present and on the amount of heat energy the coal can produce, including anthracite, bituminous, subbituminous, and lignite (highest to ...

Types of Coal. Coal is divided into four main types and these are anthracite, bituminous, sub-bituminous, and lignite. The ranking of the coal is done by the amount and the type of carbon that is present in the coal and its ability to produce heat when it is burned. The rank of the coal deposit determines the amount of pressure and …

The Global Carbon Cycle. Figure 15.6.3 15.6. 3 illustrates the global carbon cycle, the distribution and flow of carbon on Earth. Normally, the fate of atmospheric CO 2 is to either (1) dissolve in the oceans and eventually precipitate as carbonate rocks or (2) be taken up by plants. The rate of uptake of CO 2 by the ocean is limited by its ...

Bituminous/Sub Bituminous Coal. Formed from compressed lignite, bituminous coals are a dense, sedimentary rock which is usually black in colour, but can sometimes be a dark brown. These coals are widely used in the manufacturing of briquettes, and are also used in power stations, for heat and power applications in manufacturing, and to make coke.
