Coal density is among the important parameters for reservoir engineering purposes and is inserted as an input property in simulation studies. Coal density is typically less than that of conventional reservoirs and differs from seam to seam based on the given coal rank and purity [2].The bulk density of a coal consists of the matrix and the void space, with the latter being

At the standard rate this means delivered 12500 tons of washed coal per month would result in circa 625K or 7.5m pa (12500 x 50) and then transport costs are added.

Get PriceIn addition, in the south-central part of the GWA where greater coal depths (more than 500 ft) might enhance coal-bed methane retention, reported total coal accumulations are typically less than 20 ft and commonly less than 10 ft. The limited volume of coal in these areas could also reduce the coal-bed methane resource potential.
