摘要: 运用瓦斯地质理论,从煤体(埋深、厚度、变质程度)、煤体围岩、地质构造3个方面定性定量地对马依西一井3#煤层瓦斯含量进行分析,得出煤层厚度,变质程度,围岩封闭性和地质构造是该矿3#煤层瓦斯含量主要地质影响因素。Abstract: Using gas geology theory,the gas content in No.3 coal seam of Mayixi No.1 shaft was analyzed qualitatively and quantitatively from three aspects,buried depth,thickness,metamorphic degree of the coal,surrounding rock of the coal and geological structure.It was concluded that the coal seam thickness,metamorphism degree,surrounding rock sealing and geological structure were the main geological factors which affected the gas content in No.3 coal seam of this mine.
