| 摘 要： | 煤的成因类型通过煤的有机显微组成、矿物成分等来体现。从微观研究的角度出发，以各子样的显微煤岩组分统计值、镜惰比（V/I）、骨基比（F／M）、矿物质含量为依据，对西山煤田屯兰煤矿7号煤进行成因类型划分，分为4类6型，即Ⅰ-①、Ⅲ-①、Ⅲ-②、Ⅳ-①、Ⅳ-②、Ⅴ-①。自下而上对煤层划分了23个成因分层。7煤层以Ⅳ类成因类型为主，沉积了覆水森林沼泽环境。

| Abstract: | On the basis of coal genetic studies upon the No. 7 coal seam in Xishan coalfield, Shanxi Province, combined with the reconstruction of its palaeogeographic and palaeoclimatic backgrounds, coal-forming plant communities and regional sedimentary environments by systematic studying upon the different genetic marks in this coal seam, 6 types of coal genetic microfacies were recognized. By statistic analysis of the coal facies distribution over the vertical sequence of the coal column, the evolution of the coal facies of this coal seam has been briefly recovered. |
