摘　　要：采用瓦斯地质理论的方法,结合井田瓦斯地质资料和实测瓦斯数据,探讨了地质构造、地下水活动和岩浆岩侵入等因素对万年矿2#煤层瓦斯赋存的影响。结果表明:岩浆岩侵入和地下水活动造成井田煤层瓦斯含量较低,地质构造和岩浆岩侵入造成井田北部瓦斯含量小,南部瓦斯含量大,煤层瓦斯含量随深度增加而增大。地质构造、岩浆岩侵入和地下水活动是控制万年井田煤层瓦斯赋存的主控影响因素。By gas geology theory,combined with the mine gas geological data and the measured gas data,we discussed the influence of the geological structure,groundwater movement and magmatite intrusion and other factors on the Wannian Mine 2#coal seam.The results show that the magmatite intrusion and groundwater activity cause low gas content of coal mine,geological structure and magmatite intrusion cause the smaller gas content in northern and the higher gas content in southern.Coal seam gas content increases with the increasing of depth.The geological structure,magmatite intrusion and groundwater activity are the main controlling factors to control coal seam gas occurrence in Wannian Field.
