摘要
通过分析煤与瓦斯突出中各因素所起的作用,阐述了回采工作面预采煤体在移动支承压力的压移赶制作用下,其内部瓦斯运移与积聚的追集过程,该过程促进了煤与瓦斯发生突出条件的进一步形成。并在此基础上说明了走向长壁工作面煤与瓦斯突出发生在工作面中下部的原因,对深入研究和防治工作面煤与瓦斯突出有一定的指导意义。
Through analysis of the effect of every factor in coal and gas burst, we set forth the chasing and gathering process of the gas in preparative coal body to be mined, which is under the effect of moving and supporting pressure,the process accelerates the condition for coal and gas burst, on basis of which,we explained the reason why coal and gas burst often happens near the mid-part on the long coal face,to some extent ,it has guided meaning for deep research and prevention of coal and gas burst on coal face.
