History of anthracite coal mining in Pennsylvania saved up to 25% in the production of iron, and that the quality of the iron was also superior (Adams, “US Coal Industry”). By the 1850s anthracite was used in the manufacture of about half of all crude iron produced in the US. The increased efficiency of anthracite heat was also instrumental in the manufacture of metal machinery and the transformation of water into steam for machinery power (Dublin, Licht, 17). The Civil War created a shift in the makeup of the anthracite coal industry. Prior to the war, the industry involved many small-scale mines with short-term leases resulting in
History of anthracite coal mining in Pennsylvania are surrounded by sandstone ridges, which help to “protect” the anthracite (Hornberger et al., 20-2). There are four different anthracite coalfields in Pennsylvania, all located on the eastern side of the state. The Northern field is located predominantly in the Luzerne, Lackawanna, Susquehanna and Wayne Counties; the Western Middle field in Northumberland, Columbia, and Schuylkill Counties; Eastern Middle field mainly in Luzerne County but extending into Schuylkill, Carbon, and Columbia Counties; the Southern field in Carbon, Schuylkill, Lebanon, and Dauphin Counties (Latzko, 8). Anthracite differs from bituminous in usage in that it has better heat quality and fewer disadvantageous by-products,
