Abstract
Within the nonstationary, equilibrium velocity approach of the nonuniform environment mechanics, the coal and gas outburst problem is solved. Desorption of fixed gas at the surface of coal particles is described using the Freundlich and Langmuir isotherms. The constitute equation of the coal and gas mixture includes desorption of the fixed gas. The numerical analysis of the mixture flow patterns under the coal and gas outburst provided relationships of the depression and shock wave velocities and the initial concentration of particles in the coal and gas mixtures.
