摘　　要：针对演马庄矿煤与瓦斯突出问题,通过理论分析演马庄矿实测资料,得出了地质因素在煤与瓦斯突出中的控制作用。认为区域构造在不同时期应力场的变化为煤与瓦斯突出提供了动能条件,而井田内张性小断层的存在决定了煤与瓦斯突出的位置,以及煤层顶板厚0.7 m左右的构造煤、煤体结构特征和低透气性煤层顶底板岩性为煤与瓦斯突出提供了有利的条件。According to coal and gas outburst in Yanmazhuang Coal Mine, according to theoretical analysis of the Yanmazhuang Coal Mine＇s data,the role of geological factors in coal and gas outburst was obtained. It was thought that the change of the regional tectonic for different periods provides kinetic conditions for coal and gas outburst. The small tensile faults in mine shaft has determined the loca- tion of the coal and gas outburst. And about 0. 7 m tectonic coal of the seam roof, microstructure characteristics of coal,low permeability of seam roof and floor provide favorable conditions for coal and gas outburst.
