摘　　要：介绍了林华井田地质背景与龙潭组主要煤层的基本情况,分析了各主要煤层的煤岩及煤质特征。结果表明:研究区各主要煤层均为无烟煤三号,宏观煤岩类型以半亮型为主,有机显微组分以镜质组为主,4、5、9号煤层煤质较好,可用作气化用煤、动力用煤及喷吹用煤等,而13、15号煤层为中高灰、中高硫、高硫煤层,不宜直接利用。Geological background of Linhua minefiled and the basic circumstances of main coal seams of Longtan formation were introduced in this paper, the coal petrography and coal quality characteristics of main coal seams were analyzed. The results showed that： the main coal seams in the study area are the No. 3 anthracite coal, the macroscopic lithotype type is mainly the semibright coal, the organic macerals is mainly the vitrinite, the coal quality of No. 4, 5, 9 coal seam is relatively good, they could be used as gasification coal, power coal and injection coal, the coal from No. 13 and No. 15 coal seam is medium-high ash, medium-high sulfur and high sulfur coal, which is not suitable for direct use.
