摘　　要：在收集研究区最新勘查资料的基础上,对4号煤层的煤质特征进行研究,结果表明:4号煤呈黑色–褐黑色,以半亮煤型和半暗淡煤型为主,为中煤级煤第II阶段;原煤总体属低灰–中灰煤;原煤总体属特低硫煤,硫分具东部略高于西部的基本特征。On the basis of collecting the latest exploration data of the study area, the authors made the re-search of the coal quality characteristics of seam No. 4 at medium depth. The results show that the seam No. 4 is black-brown-black, semibright and semidim coal type, at the II phase of the medium rank coal. The No. 4 generally belongs to low ash-middle ash coal. The seam No. 4 belongs to extra low sulfur coal, with the characteristic of the East being slightly higher than the West.
