摘　　要：从为煤炭资源清洁高效利用提供地质保障的角度出发,系统分析了陕北石炭-二叠纪煤田吴堡矿区的煤岩煤质情况,提出了相关清洁利用建议。研究表明,吴堡矿区S1煤层属低灰、中等挥发分、特低硫、低磷、高热稳定性、强黏结煤,镜质组最大反射率平均为1.15%,煤类为中等变质阶段肥、焦、瘦煤,全矿区适用于冶金炼焦用煤24804.4万t,铸造炼焦用煤96169.1万t。Start from coal resources clean and effective utilization to provide geological security point of view,systematically analyzed coal petrology and coal quality situation in the Wubu mining area,Northern Shaanxi Permo-Carboniferous coalfield and proposed relevant clean utilization suggestions.The study has shown that the coal S1 in the mining area belongs to low ash,medium volatile matter,extra low sulfur,low phosphorus,high thermal stability and strong caking property coal.Maximum vitrinite reflectance is 1.15%average,coal ranks belong to medium metamorphism stage fat coal,coking coal and lean coal.All mining area coal adaptable for metallurgical coking has 248.044 million tons,for foundry coking 961.691 million tons.
