主要地质因素对马依西一井3^#煤层瓦斯含量影响分析

Influence Analysis of Main Geological Factors on Gas Content in No.3 Coal Seam of Mayixi No.1 Shaft

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。

Using gas geology theory, the gas content in No. 3 coal seam of Mayixi No. 1 shaft was analyzed qualitatively and quantita- tively from three aspects, buried depth, thickness, metamorphic degree of the coal, surrounding rock of the coal and geological struc- ture. 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.
