内蒙古煤炭资源煤质特征及清洁利用方向

内蒙古自治区煤炭资源丰富，拥有国家煤炭规划矿区42个，占全国煤炭规划矿区数量25.9%。为了评价内蒙古煤炭清洁转化利用途径，本文以内蒙古煤炭规划矿区为评价单元，参照特殊用煤资源潜力评价指标体系，通过对矿区主要煤层显微煤岩组分中镜质组、惰质组和壳质组和煤质主要指标中灰分、挥发分、全硫、氢碳原子及部分工艺指标进行分析，由此评价内蒙古42个煤炭规划矿区液化、气化及焦化用煤资源分布特征及清洁利用方向。结果表明：内蒙古直接液化用煤和气化用煤资源丰富，焦化用煤较少。气化用煤分布于鄂尔多斯地区的侏罗纪-石炭纪煤田，主要集中在神东大型煤炭基地，直接液化用煤分布于锡林浩特地区的早白垩纪煤田，主要集中在蒙东大型煤炭基地内，焦化用煤仅在鄂尔多斯西缘的乌海矿区分布。该研究成果将为内蒙古煤炭资源清洁高效利用及煤炭科学规划提供重要的指导意义。

CharacteristicsEvaluation on the Property of Coal Quality and Clean Utilization of Coal Resources in Inner Mongolia

The coal resources are rich in the Inner Mongolia Autonomous Region, with 42 national coal planning mining areas, accounting for 25.9% of the national coal planning mining areas. In order to evaluate the clean conversion and the utilization of coal resources in Inner Mongolia, this researchpaper takes the planned coal mining area as the evaluation unit of Inner Mongolia, refers to the potential evaluation index system of special coal resources, and analyzes the characteristics of vitrinite, inertinite and liptinitechitinite, and the ash, volatiles, total sulfur, hydrogen carbon atoms, and some process indicators to evaluate the utilization direction of liquefaction, gasification, and coking in the 42 national coal planning mining areas. The results show that Inner Mongolia has abundant coal resources for direct liquefaction and gasification, but less coal for coking. Gasification coal is distributed in the Jurassic-Carboniferous coalfield in the Ordos region, and is mainly concentrated in the large coal base in Shendong.The, direct liquefaction coal is distributed in the early Cretaceous coalfield in the Xilinhot area-where is, mainly concentrated in the large coal base in the eastern Inner Mongol area, and coking coal is only distributed in the Wuhai mining area on the western edge of Ordos. The research results will provide important guiding significance for the clean and efficient utilization of coal resources and the scientific planning of coal in Inner Mongolia.
