文中提出了采面下通风时,采空区发生自燃是否会引起采空区气体倒流的条件式。认为下行通风时采空区气体倒流现象的发生是困难的。对采面下行通风对采空区自燃的抑制作用也作了理论上的阐述。
In this paper, the condition of whether the spontaneous combustion in the goaf will cause gas backflow in the goaf when the surface is under ventilation is proposed. It is considered difficult to go back to the gob of gas during downwind ventilation. The inhibitory effect of downhole ventilation on spontaneous combustion of goaf is also theoretically expounded.
