Back when everyone used coal, the smoke was surely terrible. The notorious London smog, which used to kill hundreds of people, was based on coal smoke. Even so, in Britain today, where coal launched the Industrial Revolution more than 200 years ago, there is still a constituency for solid fuel heating. Technology has made coal a friendlier home
Due to growth in surface mining and improved mining technology, the amount of coal produced by one miner in one hour has more than tripled since 1978. Surface mining is used to produce most of the coal in the U.S. because it is less expensive than underground mining. Surface mining can be used when the coal is buried less than 200 feet underground.
When I was a kid in the mid1960s, we moved to a house that had a pile of coal in the cellar—lump coal, nice big chunks with a clean cleavage and little dust. Who knows how long it had been there, perhaps 20 or 30 years. The current heating system was a fueloil furnace, and all trace of the coal

On December 16, 2011, the Environmental Protection Agency (EPA) finalized the first national standards to reduce mercury and other toxic air pollution from coal and oilfired power plants. More than 20 years after the 1990 Clean Air Act Amendments, some power plants still do not control emissions
coal from ash. The most commonly used separation specific gravity is 1.5 to 1.6. The user may choose a different specific gravity of separation depending upon the characteristics of the raw coal and consumerdetermined clean coal specifiions. The choice of equipment for coal cleaning depends on how easy or difficult the coal is to clean.
Power plants use "scrubbers" to clean sulfur from the smoke before it leaves their smokestacks. In addition, industry and government have cooperated to develop "clean coal technologies" that either remove sulfur and nitrogen oxides from coal, or convert coal to a gas or liquid fuel. The scrubbers and NOx removal equipment are also able to
