摘要
通过理论分析和现场观测，论述了综放采空区冒落岩体碎胀特性的不同使得其内瓦斯运移形态有所区别，为治理综放面上隅角瓦斯超限问题提供了依据。
In the gob of fully-mechanized coal face, different expansion property of fallen rock leading to different flow pattern of methane in it is discussed through theoretical analysis and in-situ measuring. The results provides scientific basis for dealing with exceeding critical limit of the methane at the exit of the tail gate of fully-mechanized working face with top-coal caving.
