| 摘 要： | 从法国洛林煤田大量的煤质资料中,选取三个例子来讨论煤层煤质特征与围岩的关系。相对于泥质顶板的煤层来说,砂质顶板的煤层往往煤质变差,表现为具有较低的挥发分产率、较差的结焦性、较高的碳含量、较低的氢含量和较高的镜质组反射率。其原因是砂质顶板的煤层在成煤时期的还原程度较低,丝质组含量较高,其中的镜质组也受到氧化作用而使反射率增高。

| Abstract: | This paper discussed the relationship between coal caracteristics and enclosing lithologies of coalseams from French Lorrain coal basin.Coal quality degradation and vitrinite reflectance increase were found incoal seams enclosed or overlain by sandstones.The reasons for the quality degradation were due to the weak re-ductibility during coal seams deposition and the abundance of inertinite in these coals.oxidation of these coalsraised the reflectance of their vitrinite. |
