摘　　要：分析研究了沿空掘进巷道煤层瓦斯流动规律、分源法预测矿井瓦斯涌出量,现场实测了瓦斯残存含量,得出孟庄煤矿沿空掘进巷道实体侧煤壁一定深度内瓦斯得到充分的排放,在煤层赋存稳定,无地质构造的正常地带,沿空掘进工作面前方基本丧失了发生煤与瓦斯突出条件。By researching gas flow rules of roadway droved along gob, prediction of gas abundance with separate source method and underground pressure behavior and measuring remnant gas content, follow results were obtained ： gas within some range of coal wall of roadway drove along gob was exhausted fully; in area of stable coal occurrence and no geological tectonic, the condition of coal and gas outburst lost ahead of roadway drove along gob.

关 键 词：煤与瓦斯突出 沿空掘进 瓦斯涌出量
