  • Coal Density an overview | ScienceDirect Topics

    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 expectedly filledCoal, bituminous solid weighs 1346 gram per cubic centimeter or 1 346 kilogram per cubic meter, ie density of coal, bituminous solid is equal to 1 346 kg/m³ In Imperial or US customary measurement system, the density is equal to 84028 pound per cubic footDensity of Coal, bituminous solid in 285 units of density"Apparent Relative Density of Hard Coal The ratio ofthe mass ofa volume of lump coal to the mass ofan equal volume of water (at a specified temperature) inclusive of any voids within the lumps subjected to the test" Keywords coal; New Zealand; density; rank 464 New Zealand Journal ofGeology and Geophysics, 1986, Vol 29 THEORETICAL Twelve series of borecore samples from various coalfieldsThe apparent relative density of New Zealand coals
