The correlation between crushed coal porosity and …
Darcy flow transfers to slip flow in crushed coal in the latter stage of coal-mine methane drainage in crushed coal, and the permeability of crushed coal has a magnitude of 10 −12 –10 −11 m 2, which is rather larger than that of porous and fractured coals. The pseudo-threshold pressure gradient (TPG) decreases with the growth of …

Float-Sink (Washability) Test, Coal Analysis, Kentucky …
In a standard float-sink analysis, set amounts of the representative coal sample are crushed to a specified particle size and placed in liquids of known density or across a range of densities. Coal has relatively low density or specific gravity (1.2 to 1.5) compared to other rocks such as shale (2.4 to 2.8) or minerals such as pyrite (4.9 to 5.2).
