Excavated coal is commonly referred to as "mined coal."
Coal is a non-renewable resource, meaning it is formed over millions of years from decaying plant matter. As such, coal does not renew itself within a human time scale. Once coal is mined and used, it is no longer available for use.
Coal is also mined by underground mining, but only a portion of the coal present can be removed (holds up the roof). Coal is also mined by high wall or long wall mining, and by using large diameter augers to dig laterally into exposed seams.
