摘要
通过对晋城高煤级煤的有机质成熟度、有机质丰度和有机类型的分析， 阐明了本区高煤级煤的有机质特征。并评价了现存煤层的剩余生烃潜力和煤层在煤化过程中成煤物质产出的、并以特殊方式吸附在煤层孔、裂隙中的烃量。初步分析了高煤级煤的生烃潜势，并指出在一定的地质条件下，高煤级煤仍有较高的生烃强度。
Based on the analysis of the maturing degree,abundance and type of organic matter,the characteristics of organic matter of high-rank coal in Jincheng has been expounded.As the production of hydrocarbon was continuing during the total coalification procedure,two aspects should be considcred in evaluating the hydrocarbon-gcncrating potcntiality of coal.One is the residual hydrocarbon-generating potentiality,another one is the amount of hvdrocarbon which is absorbed in pores and fissure of coal in a special way.We have analyzed the hydrocarbon-generating potentiality of high-rank coal preliminarily,and pointed out in certain geologic conditions the high-rank coal still has very high hydrocarbon-generating strength.
