摘　　要：对我国山东、青海等地煤质较特殊的炼焦煤进行了工业分析指标、煤岩指标、焦炭光学组织和性能研究,并与同类型炼焦煤煤质进行比较。研究结果表明,焦炭光学组织能从本质上反映炼焦煤的质量,对一些煤质较特殊的煤,焦炭光学组织与工业分析指标和煤岩指标结合可更好地鉴别煤质。Based on the study of the coking coals through proximate analysis,petrology indexes,the optical texture and properties of the coke made of special coals from Shandong Province or Qinghai Province,the quality is compared with that of the same kind of coking coal.The results show that the optical texture of the coke can,in essence,reveal the quality of the coking coal,while to evaluate the quality of certain coals with special quality,a combination the proximate analysis indexes and petrology indexes is a better approach.
