Popis: The mining area of Jibei is an important coal production base, which located at the northern of Jining coalfield in Shandong province. The coal beds have the wide range of distribution and thicker sedimentary thickness in Shanxi Formation. The influence of structural feature to control the gas bearing in 3 coal bed is the paper’s important content. Two conclusions can be drawn from this study. The one is that open faults in whole area facilitate gasgascoal bed gas emitted from coal bed. The other is that closed faults in the local areas hinder gas emitted from coal bed. So, the laws are that the coal bed gas content and emission quantity are generally low in the whole mining area, but higher in parts area, and there are the abnormal gas zones at the special locations, where closed faults location.
