Coal Types, Formation and Methods of Mining epcamr

Boghead coal Consists mainly of alginite (an algae “coal maceral” dehydrogenated plant fragments). The type of original plant input, the availability of nutrients, climatic conditions, the level of the water table, the pH and Eh conditions all help to determine the type of peat that is formed (and eventually the mine drainage that

The term 'black coal' is used in Australia to refer to anthracite, as well as bituminous and sub-bituminous coals (Table 3.7). Black coal is higher in energy and has lower moisture content than brown coal. Brown coal, also called lignite, is a low-ranked coal with high moisture content that is used mainly to generate electricity.

Coal explained U.S. Energy Information Administration (EIA)

Types of coal. Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce. The rank of a coal deposit is determined by the amount of pressure and heat that acted on the plants
