9#煤是安太堡煤矿的主要可采煤层之一，宏观煤岩类型为半暗型煤。通过对煤中可溶有机质成分特征及饱和烃、芳香烃中各项生物指标化合物含量进行分析，得出：（1）样品中较高的芘含量反映煤样中的成煤母质中陆源高等植物占优势；（2）OEP指数和芳香烃中MPI指数均呈现低值，指示有机质的成熟度较低；（3）Pr/Ph值变化较大，氧芴含量稍高，指示成煤环境海侵频繁，氧化还原沉积环境交替。

The coal No.9 is one of main mineable coal seams in the Antaibao coalmine, macrolithotype of coal belongs to semidull coal. Through analyses of coal soluble organic matter characteristics and content of various biological marker compounds in saturated and ar?omatic hydrocarbons have worked out: (1) Higher pyrene content in samples reflects the predominance of terrestrial higher plants in coal-forming parent material;(2) OEP index and MPI index in aromatic hydrocarbon all present low values, indicate lower organic mat?ter maturity;(3) Higher variation of Pr/Ph values and dibenzofuran content on the high side indicate frequent transgression and alternat?ing oxidation and reduction in coal-forming environment.
