【摘要】 煤与瓦斯突出是采煤生产中一种严重的地质灾害 ,它主要发生在地质构造破坏带 .对正断层两盘瓦斯突出发生的规律研究表明 ,突出主要发生在正断层的上盘 .导致这一结果的主要原因是突出煤体主要分布于正断层的下降盘 .断层构造、构造煤分布及其与瓦斯突出的这种相互控制作用是地史上和现今构造应力场长期作用的结构 .这一规律性认识对于揭示瓦斯突出的发生机理和瓦斯突出区域预测有着重要的理论和实践意义 .讨论正断层两盘突出煤体的分布规律对于构造地质学也具有一定的启示 .更多还原

【Abstract】 Coal and gas outburst is a serious geological disaster occurred in coal mining. The outburst is mainly occurred at a failure zone of geological structure. A law study of gas outburst occurred from two walls of normal fault show that the gas outburst is occurred mainly at the top wall of the fault. The main reason for the result is that the outburst seam is mainly located in the foot wall of the normal fault. The interrelated control of the fault structure, structural coal and gas outburst is the result of a long term function in the geological history and present structural stress field. The role understanding will have an important theoretical meaning and practical meaning to release the mechanism and area prediction of gas outburst. A discussion on the distribution law of outburst seam in the two walls of the normal fault has a certain apocalypse to the geology.更多还原
