• Description:
  "Experimental work by the Bureau of Mines indicates that when a coalbed is degassed by boreholes, the flow of methane may actually increase with time. This phenomenon appears to be the result of a relative permeability effect
  
  that is, the coalbed permeability to the gas increases sharply with decreasing water saturation. This report reviews the background of experimental evidence indicating a reelative permeability effect and presents the results of a computer simulation of two-phase flow in coal." - NIOSHTIC-2
