✦ Synopsis

Measurements were made for helium and methane flowing through thin discs of coal. Flow increased with pressure differential and temperature. At room temperature the flows along the bedding plane were: helium, 873 :< lO-'O cm2 s-l atm-l, and methane 1.2 x 10mro cm2 s-l atm-l. Flow rates were 50"/, lower across the bedding plane of the coal than along the coal seam. Activation energies were 3.9 kcal mol-1 (16.3 kJ mol-1) for helium and 13.6 kcal molm1(57.0 kJ mol-l) for methane for flow measured either along or across the bedding plane.
