摘　　要：在收集研究区最新勘查资料的基础上,对5~#煤层的煤质特征进行研究,结果表明:5~#煤呈黑色-褐黑色,以半亮煤型为主,为中煤级煤第Ⅶ阶段;原煤总体属中灰煤,灰分具北高南低特征;原煤总体属中硫煤,硫分具南高北低和中间高东西两侧低的基本特征。On the basis of collecting the latest exploration data of the study area, this paper made the research of the coal quality characteristics of 5^# seam. The results showed that the 5^# coal is black-brown-black, semibright coal type, at the Ⅶ phase of the medium rank coal. Raw coal generally belongs to middle ash coal, and the ash content is high in North and low in South. Raw coal generally belongs to middle-sulfur coal, with the basic characteristics of higher in the South than in the north and higher in middle than the east and west sides.
