Numerical modeling of process of coal and methane outburst in a working face of single opening, what is driving by drill and fire system, is executed. Initiation of coal and methane outburst process in cases of various length of blastholes is observed. Change of distribution of permeability coefficient ahead of a face, pressure values and speed of formation of outburst cavity is analysed.
