河曲矿区13^(#)煤层煤质特征及液化性能评价

Coal Quality Characteristics and Liquefaction Performance of Coal No.13 in Hequ Mining Area

河曲矿区位于河东煤田最北部,13^(#)煤层为矿区主要可采煤层,在统计分析以往地质勘查煤质资料的基础上,研究河曲矿区13^(#)煤层煤质特征,分析矿区煤质分布规律,对比液化用煤主要煤质指标,综合评价13^(#)煤层液化性能。结果表明:河曲矿区13^(#)煤层以中硫-中高硫、中灰分、高挥发分长焰煤为主,洗选后可作为直接液化用煤保有资源量为15.51亿t。

The Hequ mining area is situated at the north end of the Hedong coalfield,Shanxi.No.13 coal seam is the main mineable coal seam.Based on the statistical analysis of previous exploration data in Hequ mining area,,the coal quality characteristics is studied,the distribution law of coal quality in the mining area is analyzed,and the main coal quality indexes of liquefied coal are compared with each other,the liquefaction performance of No.13 coal seam is assessed comprehensively.The result shows that the No.13 coal seam in the area is mainly composed of medium sulfur,medium-high sulfur,medium ash and high volatile long flame coal,After washing,the reserves which can be used as coal for direct liquefaction are 1.551 billion tons at least.
