摘　　要：现阶段,瓦斯是影响分层综采能力和产出质量的关键因素之一,而矿井中瓦斯的异常涌出也会导致开采工作面的日产量大幅度降低。其中,瓦斯非正常涌出,通常是指在地质构造区的断层、褶曲、火成岩等突然侵入的现象,假如这个区域的构造是由强大的应力所造成的,那么附近的煤层与瓦斯区域的气体释放将会通过它的裂隙带的开放性空间,不断地向外扩散出去,而此时该区域的气体释放会受到周围封闭裂隙的影响而无法正常扩散,这就为采煤工作面与瓦斯的协调开采带来了新的难题。当在该地区附近作业时,就极易产生瓦斯涌出异常的现象。因此,本文重点就下行通风作业时的瓦斯非正常涌出问题展开了内容分析,并就此异常情况指出处理方式,希望对今后的矿井综采工作起到重要的参考作用。At present,gas is one of the key factors that affect the capacity and output quality of fully mechanized slicing mining,and the abnormal gas emission in the mine will also lead to a significant reduction in the daily output of the mining face.Among them,abnormal gas emission usually refers to the sudden invasion of faults,folds,igneous rocks,etc.in the geological structure area.If the structure of this area is caused by strong stress,the gas release in the nearby coal seams and gas areas will continue to spread out through the open space of its crack zone.At this time,the gas release in this area will be affected by the surrounding closed fissures and cannot be normally diffused,which brings new problems to the coordinated mining of coal face and gas.When working near the area,it is very easy to produce abnormal gas emission.Therefore,this paper focuses on the content analysis of the abnormal gas emission during the downward ventilation operation,and points out the treatment methods for this abnormal situation,hoping to play an important reference role for the future fully mechanized mining work of the mine.
