| 説明 | This is a working, coal-burning steam locomotive used to head tourist trains at the Pioneer Tunnel Coal Mine in Ashland, Pennsylvania, USA. The engine, nicknamed "Henry Clay", is a narrow-gauge 0-4-0T built by Vulcan Iron Works in 1927. The photo was taken in fall 2006.Unlike most coal-burning steam locomotives, this engine utilizes anthracite coal as a fuel source. Pioneer Tunnel consists of an old surface mine plus an inactive subsurface mine - both are accessible to tourists. This mining area targeted anthracite coal, a very low grade metamorphic rock that consists of more than 90% carbon. It is black-colored, lightweight, not sooty, and breaks with a conchoidal fracture. Anthracite is harder and heavier than ordinary sedimentary coal (= lignite coal, sub-bituminous coal, and bituminous coal). It is also cleaner-burning and hotter-burning. (see: www.flickr.com/photos/jsjgeology/16319380394 andwww.flickr.com/photos/jsjgeology/16941787095) The Pioneer Tunnel Coal Mine principally mined the Mammoth Coal, the thickest anthracite coal bed on Earth.--------------------For photos of the Pioneer Tunnel Coal Mine, including the geology & anthracite coal samples, see:www.flickr.com/photos/jsjgeology/albums/72157632286478708 |
