摘　　要：针对六家煤矿WIIN_1 6-7综放工作面瓦斯涌出异常的现象,应用分源预测法预测了本工作面的瓦斯涌出量,得出其主要来源于上部顶板采空区;通过地面大气压力与井下瓦斯浓度的实测,分析其原因是由于地面大气压的变化。针对此特点采取了上部采空区钻孔抽放和本煤层采空区埋管抽放相结合的治理措施,并增加了注氮措施和采用三通和活塞的方法安装管路,取得了行之有效的效果。According to the phenomenon of abnormal gas emission of Liujia Coal Mine WIIN1 6-7 Fully Mechanized Caving Face, differentsource gas emission prediction is applied to predict the gas emission, its mainly comes from the upper roof goaf, through the ground atmospheric pressure and underground gas concentration measurement, and due to the ground atmospheric pressure changes. Borehole gas drainage in upper goaf and the coal goaf buried tube drainage combined control measures are adopted. Nitrogen injection measures are increased. T-junction and piston are used to install piping. Effective results are gotten.
