摘　　要：为进一步提升煤矿生产的安全性,避免瓦斯涌出超标导致爆炸事故的发生,以某矿井的02号煤层为例,在对工作面涌出瓦斯特性参数分析的基础上,根据瓦斯抽采方法的选择原则,并结合煤层赋存条件和巷道布置情况,分别对开采层、邻近层和采空区的瓦斯抽采方法进行设计;最后,对工作面的瓦斯抽采效果进行预测,并取得理想结果。In order to further improve the safety of coal mine production and avoid the occurrence of explosion accidents caused by excessive gas emission, taking No.02 coal seam of a coal mine as an example, based on the analysis of gas emission characteristic parameters of the working face, according to the selection principle of gas extraction method, and in combination with the occurrence conditions of coal seams and roadway layout, the gas drainage methods of mining layers, adjacent layers and goaf are designed respectively.Finally, the gas drainage effect of the working face is predicted and ideal results are obtained.
