摘　　要：为了研究富油煤的基础煤质特征及成煤环境特征,以陕北地区的三个主要煤区—黄陇区域、子长区域和榆神府区域的富油煤为研究对象,根据国家标准或行业标准对样品进行煤质分析、灰成分分析、焦油热解产物分析。研究结果表明:陕北富油煤煤质优良,各项指标均优于动力煤要求,是干馏煤气的理想原料。低温干馏所得焦油中各类组分含量稳定,不同样品间虽有差异但存在内在规律性。该地区富油煤形成于稳定的沉积环境,靠近陆源区。To study the basic coal property characteristics and coal-forming environmental features of tar-rich coals,this research focuses on the tar-rich coals from three major coal regions in northern Shaanxi—Huanglong,Zichang,and Yushenfu.The samples were analyzed for coal quality,ash composition,and tar pyrolysis products according to national or industry standards.The results show that tar-rich coal from Northern Shaanxi has excellent coal quality,with all indicators surpassing the requirements for thermal coal,making it an ideal raw material for producing gas through dry distillation.The content of various components in the tar obtained from low-temperature dry distillation is stable,and although there are differences among different samples,there exists an inherent regularity.This type of coal was formed in a stable sedimentary environment close to terrestrial source areas.
