摘要
通过分析矿区实测数据资料和前人研究成果,本文对影响大兴井田含气量的因素进行研究。研究认为,大兴井田整体构造对含气量有一定程度影响;随着埋藏深度的增加,含气量有增加的趋势;岩浆岩发育地区,含气量普遍较高;区内主要发育长焰煤、气煤、贫煤等,煤阶越高含气量越高;大兴井田水文地质条件对煤层气富集有一定的促进作用。总体来说,煤层埋藏深度和井田内岩浆岩发育情况是影响大兴井田瓦斯含气量的主要因素。
This paper studies the factors that influence gas content of Daxing coal field on the basis of analyzing measured data of the coal mining area and previous academic findings. It argues that the overall structure of Daxing coal field can influence gas content. The burial depth of coal is positively related to gas content. The gas content is generally higher in area with magrnatic rock development, and the area with the development of long frame coal, gas coal, lean coal, ere also has higher gas content. The hydrogeology condition of Daxing coal field is favorable to CBM enrichment. On the whole, the burial depth of the coal seams and the development conditions of magmatic rocks in the coal field are the major factors that influence the gas content of Daxing coal field.
