Coal Types, Formation and Methods of Mining

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 comes from the bed).
