摘　　要：五花洞煤矿地处五花洞背斜推覆体南西端,下二叠统栖霞组梁山段产可采煤层1层,厚0.60~4.26 m,煤类别为中高灰中至高硫低磷长焰煤,对煤层煤岩特征、煤质特征进行分析,结合沉积环境对煤质特征影响进行探讨。在采取改进采矿工艺、选矿脱硫、配煤等降硫措施后,该长焰煤可以用作发电燃料,还可用作烧石灰、砖瓦或民用燃料。Wuhuadong Coal Mine is located at the southwest end of Wuhuadong anticline nappe.There is one minable coal seam in Liangshan section of Qixia Formation of Lower Permian,0.60-4.26 m thick.The coal is medium high ash,medium to high sulfur and low phosphorus long flame coal.The coal petrographic characteristics and coal quality characteristics of the coal seam are analyzed,and the influence of sedimentary environment on coal quality characteristics is discussed.After taking measures such as improving mining processes,beneficiation desulfurization,and coal blending to reduce sulfur,the long flame coal can be used as a fuel for power generation,as well as for burning lime,bricks and tiles,or as a civilian fuel.
