摘　　要：绍根矿区是内蒙古白垩系重要的煤田之一,煤岩煤质特征的分析对其资源评价及清洁利用均有较大意义。在对以往勘查钻孔的煤质化验数据统计分析的基础上,对绍根矿区主采煤层5号煤层的煤岩、煤质特征进行了详细分析;阐述了该矿区显微煤岩组分和灰分、挥发分、硫分、氢碳原子比等煤质指标的分布情况;参照直接液化和气化用煤的评价要求对5煤层的煤气化、煤液化的相关指标进行了划分。研究结果显示,绍根矿区中部煤炭资源较适合作为直接液化用煤,矿区南部、北部煤炭资源可作为流化床气化工艺用煤。Shaogen mining area is one of the important Cretaceous coal fields in Inner Mongolia, the analysis of coal petrology and coal quality characteristics is of great significance to its resource evaluation and coal clean utilization. Based on the statistics of coal quality test data from previous exploration boreholes, this paper analyzes in detail the coal petrology and coal quality characteristics of No. 5 main mining coal seam in Shaogen mining area, and expounds the micro coal rock components, ash, volatile, sulfur, hydrogen carbon atomic ratio, and other coal quality index characteristics in this mining area;according to the evaluation requirement of coal for direct liquefaction and gasification, the related indexes of coal liquefaction and coal gasification of No. 5 coal seam are divided. The results show that the coal resources in the central part of Shaogen mining area are suitable for direct liquefaction, and the coal resources in the south and north parts of the mining area can be used for fluidized bed gasification process.
