摘　　要：本文在对南桐矿区地质构造与煤和瓦斯突出关系详细研究的基础上，论述了地质构造及其演化对煤和瓦斯突出的控制。主要结论有：（１）构造应力场具有主控作用；（２）构造演化造成了煤变质程度、煤体破坏程度和煤层瓦斯含量差异；（３）构造演化还造成了现今构造应力和瓦斯压力分布的差异；（４）地质构造及其演化控制了煤和瓦斯突出的区域性分布。Control of geological structure and its evolution on coal and gas outburst has been discussed based on detail study on the relations between geological structure and coal and gas outburst in Nantong Mining Area. The conclusions are: (1) tectonic stress has the main controlling effect; (2) structural evolution has caused the lateral variation of coal metomorphic degree, coal broken degree and the gas content of coal seams; (3) structural evolution has also caused the inequable distribution of earth stress and gas pressure; (4) geological structure and its evolution has cotrolled the inequable distribution of coal and gas outburst.
