摘要： 在收集研究区最新勘查资料的基础上，对11^#煤层的煤质特征进行研究，结果表明：11^#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，灰分等值线呈“耳”状，NNE向延伸，由SE向NW灰分逐渐
变高；原煤总体属高硫煤，硫分等值线图呈“X”型，具北东～南西方向高，北西～南东方向低的分布特征。

Abstract: On the basis of collecting the latest exploration data of the study area, this paper made the research of the coal quality
characteristics of seam No.11. The results showed that the seam No.11 is black-brown-black, semibright coal type, at the 喻
phase of the medium rank coal. Raw coal generally belongs to middle ash coal, ash content contour shows "ear" type, and ash
yield gets higher from SE to NW, NNE to extension. Raw coal belongs to high-sulfur coal, and shows "X" type in sulfur contour
map, with the basic characteristics of high in NE to SW, low in NW to SE.

Key words: coal quality characteristics; No.11 coal seam at medium depth; Longting mining area; Weibei P-C coalfield
