Geological structure is the main control factor of coal and gas outburst. Characteristics and types of coal and gas outburst usually have great different in regions of different structural deformation patterns. Based on the research of the characteristics of structural deformation in the coal and gas outburst zones, and combined the gas geology theory and the gas geology parameters, the influences of structural deformation on coal and gas outburst types was also further analyzed. The results show that the structural deformation can be divided into three types according to its different formation mechanisms, and it was respectively called as press-out type, press-in type and superposed type in this paper. The coal and gas outburst type is different in areas of different structural deformation type.
