摘　　要：针对内蒙古二道岭矿区构造复杂,构造部位及影响带多显示瓦斯异常和煤与瓦斯突(喷)出多发、易发等特点,应用瓦斯地质理论,重点研究构造对煤层瓦斯赋存和突(喷)出的控制作用及规律。研究表明,"封闭型"压性、压扭性构造为煤层瓦斯的保存提供了良好的"封存效应",是控制区内煤层瓦斯含量整体较高和不均衡分布的关键因素;构造类型、性质和组合方式共同控制着煤层瓦斯的分区、分带和煤与瓦斯突(喷)出范围及机率。In view of the complex structure in the study area, tectonic position and tectonic zone with more display abnormal gas and coal and gas outburst （spray） of multiple, prone to wait for a charac- teristic. By applying theory of gas geology, the control of structure to coal seam gas occurrence and gas outburst （spray） and its regulation were studied. Studies show that ＂closed＂ eompressional and shear structure of coal seam gas pressure preservation provides a good ＂sequestration effect＂ , which is im- portant factor to control the area of coal seam gas content being high and uneven distribution; Con- struction type, nature and combinations jointly control seam gas partition, zoning and sudden coal and gas （spray） the scope and probability.
