     · Bituminous coals are black, shiny, and generally are a mediumrank coal. Bituminous coals generally have calorific values above 11,500 Btu/lb and volatile matter below 14% (ASTM, Jackson, 1997). In the Illinois Basin (and western Kentucky), however, the lower rank end of what are termed bituminous coals in the United States have calorific values of 11,100 to 11,300 Btu/lb.

    comparisons with whole seam coal samples. Photooxidation and Luminescence Analysis Luminescence spectral analysis, measurement of emission intensity at a given wavelength (600 nm) and photooxidation will be performed initially using a Leitz Orthoplan MPVI1 microscope. Basic luminescence properties of the vitrinite from each coal will be measured under a nitrogen atmosphere. .

    Small slab of bituminous coal (while shiny it is quite soft, thus bituminous and not anthracite). A relatively thin seam of bituminous coal can be found in Licking County, Ohio. Not economically viable to mine. Collected from the Licking River behind the Velvet Ice Cream factory. The loion is a 30 minute drive from the more famous Flint Ridge area. As a river find, the specimen could have ...

    from eight coals ranging in rank from high volatile B to low volatile bituminous. Every effort will be made to collect fresh coals from the field and to maintain them under conditions that limit their exposure to atmospheric oxygen, to drastic changes in temperature and relative humidity, and exposure to direct sunlight. Moreover, where practical, samples of coal which have been exposed and ...

     · Bituminous coal was first mined in Pennsylvania at "Coal Hill" (Mount Washington), just across the Monongahela River from the city of Pittsburgh. The coal was extracted from drift mines in the Pittsburgh coal seam, which outcrops along the hillside and transported by canoe to the nearby military garrison. By 1830, the city of Pittsburgh consumed more than 400 tons per day of bituminous ...

    What are the types of coal?

    Bituminous: Bituminous coal is a middle rank coal between subbituminous and anthracite. Bituminous coal usually has a high heating (Btu) value and is used in electricity generation and steel making in the United States. Bituminous coal is blocky and appears shiny and smooth when you first see it, but look closer and you might see it has thin, alternating, shiny and dull layers. Subbituminous ...
