Estimating the Heat of Methane Desorption from Coal by Means of the Temperature Change
A method is proposed for assessing the heat of methane desorption from coal on the basis of the temperature change in desorptional induction. The...
-
Shrinkage of the Coal Bed at the Face
Gas depletion results in shrinkage of the coal bed and hence in distortion of the stress–strain state near the face. The swelling of the coal is...
