söetööstuse
Söetööstus refers to the industry involved in the extraction, processing, and distribution of coal. Coal, a combustible black or brownish-black sedimentary rock, is primarily composed of carbon along with variable quantities of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Its formation occurred over millions of years from the remains of dead plant matter buried under layers of sediment.
The history of söetööstus is long and intertwined with human industrial development. Coal was used for heating
The process of söetööstus involves mining, which can be carried out through underground or surface methods,
The primary applications of coal within the söetööstus are electricity generation, steel production (as coke), and
