摘　　要：为保障深水平矿井自然风压的有效控制和利用,采用现场实测的方法,以滕东生建煤矿一采区为例,对自然风压的变化规律及由于其变化导致采空区漏风的现象进行了研究。研究表明:深水平矿井自然风压全年变化规律形如正弦曲线,自然风压的变化导致采空区存在规律性的进漏风趋势变化,当自然风压减小时,采空区密闭处密闭内外压能差变大,漏风趋势明显,出风量增加,若采空区密闭处进漏风趋势为进风,则密闭处进风趋势减弱,甚至反向。当自然风压增大时,采空区密闭处密闭内外压能差减小,进风趋势明显,进风量增加,若采空区密闭处进漏风趋势为漏风,则密闭处漏风趋势减弱,甚至变为进风。In order to ensure the effective control and utilization of the natural wind pressure in deep mines, the field measurement method was adopted. Taking the mining area of Tengdongshengjian Coal Mine as an example,the variation law of natural wind pressure and the phenomenon of air leakage in the goaf due to its change were carried out the study. The research shows that the natural variation of natural wind pressure in deep horizontal mines is like a sinusoidal curve,and the change of natural wind pressure leads to the regular change of the trend of the inlet and outlet winds in the goaf. When the natural wind pressure is reduced,the gap between the inner and outer pressures of the closed area of the goaf is increased,the air leakage trend is obvious,and the air volume is increased. If the trend of air leakage into the air in the confined area is the incoming air,the air intake trend in the airtight area is weakened or even reversed. When the natural wind pressure increases,the gap between the inner and outer pressures of the closed area of the goaf is reduced,the wind entering trend is obvious,and the air intake is increased. If the air leakage trend in the closed area of the goaf is air leakage,the air leakage trend in the airtight area is weakened,and even becomes the air inlet.
