COMPUTATIONAL MODELING OF THE DEGASSING OF COAL SEAMS

A physico-mathematical model of methane desorption and fi ltration in an undisturbed coal seam in the vicinity of a degassing well is proposed. The results are presented on calculations of the change in the specifi c methane release from this well and in the average content of methane in the coal mass in its vicinity in a degassing time of up to 6 years. A good agreement between the results of calculations of the model and the engineering formulas has been obtained.
