Title: In-situ diffusion parameter for the Pittsburgh and Pocahontas No. 3 coalbeds. [15 refs]

Technical Report ·
OSTI ID:7231667
;

The importance of diffusion in controlling the emission of methane in mines is examined. An in-situ diffusion parameter is defined and calculated for a hypothetical unfractured lump of coal in the Pittsburgh and Pocahontas No. 3 coalbeds. The values obtained are similar to those obtained with lump coal in laboratory experiments.
