摘　　要：通过煤岩组分及镜质体反射率测定,山西白额勘探区10#煤层有机显微组分以镜质组为主,镜质组最大反射率在2.4左右,为较好的气源岩。煤层的顶底板基本为粉砂质泥岩或泥岩,能有效阻止煤层气的逸散,为气体的保存提供了较好的封闭条件。现场钻井取样,进行瓦斯解析实验表明,本区10#煤层的煤层气含量较丰富,具有较好的煤层气勘探和开发潜力。In this paper,through researching macerat and vitrinite reflectance determination, we know the organic macerals of 10# coal mainly is vitrinite. The vitrinite maximum reflectance is about 2.4. thence,10# coal bed is a better gas source rocks; coal seam roof and floor is ssilty mudstone and mudstone, so they can effectively prevent cbm dissipation . They provide a better preservation condition for the gas. drilling coal sample to experiment at the scene , the gas experimental results show that the cbm content is richer. Therefor ,10# coal bed has a good potentiality for cbm exploration and development.
