crushed coal properties

The correlation between crushed coal porosity and permeability …

The results show that the permeability properties of crushed coal are closely related to the coal porosity, methane pressure, and axial stress. 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 ...
