the process of subsurface coal extraction and thermal coal processing. Purpose Coal is used for its potential heat energy when burned and since the 1880s has been widely used to generate electricity in power plants. To to generate electricity coal is first burned inside a power plant and the heat generated by the coal is then used to heat water.

Coal production continues to grow globally due to the demand for low cost energy and iron and steel, as well as cement. Coal, based on the current extraction rates, will last about 115 years longer than conventional oil and gas reserves, with an estimated 1.1 trillion tonnes of proven coal reserves worldwide. Ten countries are responsible for 90% of the total global coal production.
