低瓦斯矿井通风系统及通风能力合理校定研究

Study on reasonable calibration of ventilation system and air delivery volume of low gas mine

结合木瓜矿低瓦斯矿井的特征,对矿井初期风量、矿井后期风量以及矿井通风负压和等积孔进行了校验,从矿井用风地点有效风量、矿井通风网络能力等方面进行验证,井下各用风点风量、风速、风阻均能够满足矿井安全生产要求。

Based on low gas mine features of Mugua Mine, initial and late air volume, negative pressure and equivalent orifice of the mine were checked, effective ventilation and ventilation network capacity of the mine showed that Wind volume, wind speed, wind resistance of all wind points met the needs of safe mining.
