摘　　要：在矿井通风中必须提供足够的通风动力以克服空气阻力,才能促使空气在井巷中流动。矿井通风动力有自然条件形成的自然风压和由通风机提供的机械风压2种。自然风压是由进回风井空气柱重力差产生,井筒垂深一定时自然风压的大小、方向由空气密度差决定。为探讨自然风压对大红山铁矿I号铜矿带通风的影响,通过分析进回风井空气温度、湿度数据,利用相关公式计算出矿井自然风压。自然风压作为一种不稳定的动力源,其计算和研究对指导矿井通风安全和节能降耗有重要意义。In the mine ventilation,sufficient ventilation power must be provided to overcome the air resistance to promote air flow in the well.The mine ventilation power has two kinds of natural wind pressure formed by natural conditions and mechanical wind pressure provided by the fan[1].The natural wind pressure is generated by the gravity difference of the air column entering and returning to the wind well.When the depth of the wellbore is constant,the magnitude and direction of the natural wind pressure are determined by the difference in air density.In order to investigate the influence of natural wind pressure on the ventilation of No.1 copper belt in Dahongshan Iron Mine,the natural wind pressure of the mine was calculated by analyzing the air temperature and humidity data of the incoming and returning wells.As an unstable power source,natural wind pressure is of great significance for guiding mine ventilation safety and energy saving.
