Posted by Paul Flaherty on October 20, 2012  Hummm… I wonder what they test for; cleanliness, btu value..?? Posted by Vernon McCarthy on October 20, 2012  I'm not sure of what they are testing for, but you can rest assured it involves a computer. Posted by sirmartinfrobisher on October 20, 2012  Could it also be the amount of pulverisaton? Posted by John Simpkins-Camp on October 21, 2012  Fascinating!! I have never heard of this practice or seen it documented! The things you see on this site!! (Something new for the model railroaders to add!). Posted by Mitch Solacz on October 21, 2012  The mines I have been to usually check BTU, ash content and moisture content to ensure that the coal meets customer requirements. Posted by on October 21, 2012  This is pretty much standard practice. Depending on the customer specs, they test for sulphur content, btu, ash, moisture, etc. Most of the time the samples are taken in a less obvious manner, but it's always done. Nice shot of an interesting aspect of the coal mining business! Posted by Paul Flaherty on October 21, 2012  That about answers it.. thanks Ron & Mitch Posted by Chase Gunnoe on October 24, 2012  Very cool, Craig! A taste of Appalachia!
