It is noted that when using the first method of ventilation, difficulties arise with regard to the removal of methane from the bottom-hole part of the working area, associated with the occurrence of convective thrust that lifts light gas up under the roof and pushes it against the movement of air in the direction of the mouth of the mine. An analytical model of the convective movement of methane in an inclined dead-end mine has been developed, on the basis of which a quantitative assessment of the minimum air supply rate for face ventilation has been made, in which all the released methane is removed by suction into the pipeline, without its part accumulating under the roof of the mine with a gradual spread of the methane-air mixture towards the mouth.
