  • Coal Density an overview ScienceDirect Topics

    The authors pointed out that at 5% ash content, Powder River Basin sub-bituminous coal has a dry-basis density of 1.4 g/cm 3; however, with a moisture content of 27% and ash content of 5%, the density is only 1.33 g/cm 3. This density value difference indicates how crucial the accurate moisture content is for a reliable estimate of gas-in-place.

    The Powder River Basin is the largest coal mining region in the United States, but most of the coal is buried too deeply to be economically accessible. The Powder River Basin coal beds are shaped like elongated bowls and as mines expand from east to west in the Powder River Basin, they will be going "down the sides of the bowl".
