  • Quantifying coal: How much is there?

    How much coal is there? And how much of that coal is economically practical to mine? The short answer for Alaska: There is only a few percent of the nation's recoverable reserves in Alaska, but there is a vast but little explored coal resource in the arctic that may mean Alaska has half or more of the coal in the US.. The details are complicated, depending not only on the underlying geology ...

    The map below shows the location of U.S. coal reserves according to their grade (i.e., heat content). Anthracite deposits, which are the highest grade, are mainly found in the Appalachian Mountains, but these relatively small deposits have largely been mined out. Up until the 1970s, the vast majority of coal mined in the U.S. came from the bituminous deposits in the Appalachia area (Ohio ...

  • Anthracite Coal Characteristics and Applications

    Anthracite coal, mined from the planet's oldest geological formations, has spent the longest time underground. The coal has been subjected to the most pressure and heat, making it the most compressed and hardest coal available. Hard coal contains greater potential to produce heat energy than softer, geologically "newer" coal.
