文章概述了矿井停风、反风期间的瓦斯涌出规律:反风时风流排出瓦斯量减少;恢复正常通风时排出瓦斯量增大,其涌出曲线呈地堑形;反风时瓦斯浓度比正常时低;采区反风率愈低,工作面风量愈小,则矿井中反风排放瓦斯量愈小, The paper summarizes the gas emission rules during stop-wind and anti-wind periods in the mine: the amount of gas discharged from the wind flow during the anti-wind period is reduced; the amount of discharged gas is increased when the normal ventilation is resumed, and the gushing curve is a graben; Normal low; mine area, the lower the anti-wind, the smaller the air flow on the face, the mine in the amount of anti-wind exhaust gas is smaller,
