摘　　要：贵州省五轮山矿区的含煤地层为龙潭组,钻孔煤心化验资料和瓦斯解吸数据、煤样压汞试验表明,可采煤层显微煤岩类型以微镜惰煤为主,煤化作用符合深成变质作用的一般规律,煤体原生结构煤占优势。主煤层孔隙结构特征的孔容和孔表面积差异较大,因此可采煤层含气较高,解吸能力相对较弱。The coal-bearing strata belong to Longtan Formation in the Wulunshan mine area, Guizhou Province. The borehole coal core testing information and gas desorption data, coal sample mercury injection experiment results have demonstrated that the microlithotype of mineable coal seams is mainly vitrinerite, the coalification is tally with general rule of hypozonal metamorphism, primary structural coal is predominated in coal mass. Pore volumes and pore surface areas have remarkable difference in main coal seam pore structural characteristics, thus mineable coal seams have higher gas content and weaker desorption ability relatively.
