摘　　要：地质构造对煤与瓦斯突出具有明显的控制作用,以往多是定性的分析和统计研究。通过构造应力场理论及相似模拟实验,分析了构造应力场与煤及瓦斯突出的关系。对相似实验结果进行对比分析,结合煤及瓦斯突出与褶曲构造展布关系实例,研究了褶曲构造不同部位应力分布特征及其对瓦斯突出的控制作用。结果显示:背斜翼部挤压区和转折区是煤及瓦斯突出的最危险地带;背斜轴部区一般不会出现严重的煤及瓦斯突出。Mostly,researches on control function of geological structure to coal and gas outburst were qualitative and statistical analysis.The paper applied the theory of tectonic stress field and the simulation experiment to analyze and study the relation between tectonic stress field and coal/gas outburst.In combination with actual case of relationship between coal/gas outburst and fold distribution,the authors studied the characteristics of stress distribution in different parts of fold and their control on coal/gas outburst,providing a new thinking for coal/gas outburst control.
