摘　　要：以全面梳理准东煤田煤炭资源煤质特征,促进准东煤田优质煤炭资源的清洁高效利用为目标,以准东煤田中侏罗统西山窑组主要煤层B1为研究对象,采用以往煤田地质勘探钻孔数据分析结合系统采样和分析测试,对B1煤层的煤质特征进行详细研究,利用GIS软件绘制主要煤质指标的等值线分布图,总结煤层灰分、硫分、挥发分、氢碳原子比(H/C)、煤灰成分的分布规律。准东煤田B1煤层具有惰质组含量高、镜质组含量较低的特点,以低灰、特低硫、中高挥发分煤不粘煤(31BN)为主,氢碳原子比相对稳定,大部分地区集中在0.60附近,煤灰成分基本为钙质灰分。煤炭的清洁利用类型大部分以适合水煤浆气化为主,部分适合流化床气化,少量适合液化。原煤洁净等级为Ⅲ级,属较好洁净煤;浮煤洁净等级为Ⅱ级,属好洁净煤。本文提出准东煤田煤炭资源的绿色开发建议,对该区煤炭资源的洁净高效利用和生态环境协调发展具有指导作用。To comprehensive combing Zhundong coalfield of coal resources,coal quality characteristics,promote quality Zhundong coalfield,the clean and efficient utilization of resources as the goal,take the B1 coal seam of the middle jurassic xishanyao formation in the main coal seam of Zhundong coalfield as the research object,use the past coal geological exploration drilling data analysis system of sampling and analysis,the detailed study on the B1 coal quality characteristics of the coal seam,the isoline distribution maps of main coal quality indexes were drawn by GIS software,and the distribution laws of coal ash,sulfur,volatile,hydrogen/carbon atom ratio(H/C)and coal ash composition were summarized.B1 coal seam in Zhundong coalfield is characterized by high inertinite content and low vitinite content.It is dominated by low ash,super low sulfur and medium-high volatile coal(31BN).Hydrogen carbon atom ratio is relatively stable and most areas are concentrated around 0.60,the composition of coal ash is calcareous ash.Most of the types of clean utilization of coal are suitable for coal-water slurry gasification,some are suitable for fluidized bed gasification,and a small amount is suitable for liquefaction.The clean grade of raw coal isⅢ,which belongs to better clean coal;the clean grade of floating coal is gradeⅡ,which belongs to good clean coal.The suggestion of green development of coal resources in zhundong coalfield is put forward,which has guiding effect on clean and efficient utilization of coal resources and coordinated development of ecological environment.
