摘　　要：季节变化和昼夜交替会引起地面大气压变化,地面大气压的变化使得矿井封闭区域内外压力相对发生变化,并导致工作面的瓦斯异常涌出。论文分析了大气压变化和瓦斯异常涌出之间的关联性,指出弄清封闭区域临界压力的方法,通过采取采空区瓦斯抽采、工作面均压通风、巷道喷涂堵漏风等技术措施,有效抵御了大气参数变化引起的瓦斯异常涌出。Seasonal variations and diurnal alternation can cause changes in surface atmospheric pressure.The change of surface atmospheric pressuremakes the pressure inside and outside the closed area of themine relativelychange,and leads to the abnormal gasemission of theworking face.The paper analyzes the relationship between atmospheric pressure change and abnormal gas emission,and points out the method of clarifying the critical pressure in closed area.The abnormal gas emission caused by the variation of atmospheric parameters is effectively resisted by adopting the technical measures of gas drainage in goaf,uniform pressure ventilation inworking face and air leakage stopping by spraying in roadway.
