Abstract
The possibility of determining the coefficient of permeability of coal seams on debit degasification wells with different orientation with respect to the main fracture systems based on the Darcy law for a fractured porous media. The technique of calculating the permeability coefficient of coal seams in their natural state on the basis of measured values of gas emission from the inner surface of the wells. The concept of permeability tensor and its relationship with the system of cracks in the coal array. The comparative evaluation of gas permeability coefficients calculated for certain strata of Kuzbass in different directions vectors of gas flows. It is recommended to use the proposed methodology for the design of degassing prepared for extraction of coal seams in order to reduce the natural gas content to a predetermined level ensuring the safety of underground coal mining.
