  • Bituminous Coal Characteristics and Applications

    Jan 29 2020 · Bituminous coal combustion releases more pollution into the air than sub-bituminous coal combustion but due to its greater heat content less of the fuel is required to produce electricity. As such bituminous and sub-bituminous coals produce approximately the same amount of pollution per kilowatt of electricity generated.

  • AnthraciteWikipedia

    More than 2 000 people were employed in the mining of anthracite coal in 1995. Most of the mining as of that date involved reclaiming coal from slag heaps (waste piles from past coal mining) at nearby closed mines. Some underground anthracite coal is also being mined. Countries producing HG and UHG anthracite include Russia and South Africa.
