通风阻力（ventilation resistance）是指在通风工程上，空气沿井巷流动时，井巷对风流所呈现的阻力。通风阻力包括摩擦阻力和局部阻力。通风阻力大小与通风压力大小相等，方向相反。因此，只要能计算出通风阻力值，就能确定矿井通风所需要的压力值。
选择矿井主扇机，需依据矿井所需风量、通风阻力。
Choosing main fan in mine is according to the amount of wind that the mine well needs and the well ventilated resistance.
王家寨煤矿为中央并列式通风，漏风量较大，主井通风阻力较大。
Retrograde ventilation is used for Wangjiazhai coal mine, both air leakage and ventilation resistance of the main shaft are largish.
根据千秋矿通风阻力分布和生产布置，对通风方案进行比较，优化选择。
According to the ventilation resistance distribution and production plan, the optimum ventilation plan was selected after comparison.
