吐哈盆地艾丁湖斜坡带主煤层煤质特征及利用方向

Coal quality characteristics and utilizing directions of main coal seam in Aydin lake slope of Turpan-Hami Basin

基于艾丁湖斜坡带主煤层厚度大、煤层稳定、煤炭资源量较大,从煤的物理性质、煤岩特征、化学性质以及工艺性能等方面进行了分析。分析表明:该区主煤层煤具有低-特低灰分、高挥发分、特低硫、特低磷、高热值、不具黏结性的性质,煤类为褐煤,是优质的动力用煤、液化和气化用煤、化工用煤及民用煤。

The relatively good thickness and stability of main mineable coal seam provides relatively large coal resources reserves.After the physical property,lithotype,chemical property and technical performance of coal were analyzed comprehensively.It was considered that the main mineral coal has characteristics such as middle moisture,low to extra-low ash,high volatile matter,extralow sulfur and phosphorus,high calorific value and lack of caking property,so that is a kind of lignite which is suitable when used as high-quality steam coal,liquefaction and gasification coal,chemicals processing coal,and domestic use coal.
