摘　　要：针对目前国内外对煤与瓦斯突出事故研究现状,基于鹤岗矿区益新矿发生的突出事故,结合鹤岗矿区构造特征和黑龙江东部区域构造应力场,从发生突出事故时的地应力、构造煤及瓦斯等因素出发,对煤与瓦斯突出的致因进行了研究分析,构造应力提供动力条件,瓦斯膨胀引发链锁效应,构造煤厚度与突出强度呈正相关,认为益新矿发生的突出事故是构造应力、构造煤与瓦斯的综合作用的结果。In view of the present research situation of coal and gas outburst accidents at home and abroad,basing on the coal and gas outburst accident of Yixin Coal Mine of Hegang Mining Area,we analyze the coal and gas outburst accident causation which includes geostress,tectonic coal and methane,combine with the tectonic feature of Hegang Mining Area and tectonic stress field in eastern Heilongjiang. Supported with the tectonic stress and the chain of destruction of methane expansion,the positive correlation between tectonic coal thickness and intensity of outburst is dicoverd. It concludes that coal and gas outburst accident of Yixin Coal Mine is resulted by the comprehensively effect including tectonic stress,teconic coal and methane.
