摘　　要：六盘水井田龙潭煤系为腐植煤类。宏观煤岩类型以半亮煤为主。无机显微组分以粘土矿物和石英为主。有机显微组分含量在69.20%~93.43%,以镜质组为主。最大镜质体反射率0.891%~1.930%,一般为中煤级煤Ⅲ~Ⅴ。此类煤层利于煤层气的富集高产。The Longtan coal series in Liupanshui coalfield is humus coal.The macro coal type is mainly semi-bright coal.Inorganic microscopic components are mainly clay minerals and quartz.The content of organic micro-components ranges from 69.20%to 93.43%.The maximum reflectance of vitrinite is 0.891%~1.930%,which is generally medium coal grade coalⅢ~Ⅴ.Such coal seams are conducive to the enrichment and high production of coal seam gas.
