microlithotype

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.

结果表明,裂隙在不同显微岩类型体中的分布存在较大的差异,同时裂隙分布的位置与显微岩类型的组合序列有关。

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.

摘要综合利用显微地层学和统计学方法，以河东田中北部8＃层为，研层显微岩类型与层裂隙分布的关系。
