| 摘 要： | 综合利用显微地层学和统计学方法,以河东煤田中北部8#煤层为例,研究了煤层显微煤岩类型与煤层裂隙分布的关系。结果表明,裂隙在不同显微煤岩类型煤体中的分布存在较大的差异,同时裂隙分布的位置与显微煤岩类型的组合序列有关。其结果对煤层气资源评价和煤层渗透性预测具有重要的指导意义。

| Abstract: | The relationship between microlithotype and the distribution of cleat in coal bed is discussed through a case from Hedong coalfield, combining microstratigraphy and statistics methods. The result shows that the cleat density in coal bed varies in different microlithotype, and the occurrence of cleat is relevant to the grouping sequence of microlithotypes. It is significant to prediction of coalbed permeability and resource evaluation of coalbed methane. |

| Keywords: | coal bed microlithotype cleat relationship |
