矿井反风是防止矿井火灾扩大的非常措施。经验证明,入风井筒发生火灾时,反风得当是可以减少伤亡的。因此,《煤矿安全规程》作了规定:矿井主要扇风机必须装有反风设备;能在10分钟内改变巷道的风流方向,反风的风量不小于正常供风量的60%;每年至少要进行一次演习等等。事物总是一分为二,有利也有弊。反风的不利之处,在于增加附属设备。尤其是因为反风量不小于正常供风量60%的规定,使矿井不得不采取反风道。这不仅使扇风机装 Anti-wind mine is to prevent mine fires to expand the extraordinary measures. Experience has shown that when a fire occurs in the shaft of the air intake shaft, appropriate anti-wind can reduce casualties. Therefore, “Coal Mine Safety Regulations” made provision: Mine main fans must be equipped with anti-wind equipment; can change the direction of the flow of the roadway within 10 minutes, the amount of wind against the wind is not less than 60% of the normal supply of wind; at least each year A drill and more. Things are always divided in two, there are advantages and disadvantages. The downside of anti-wind lies in the increase of ancillary equipment. Especially because the anti-wind volume is not less than 60% of the normal supply of wind provisions, so that the mine had to take the anti-wind duct. This not only fan fan installed
