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.

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＃层为例，层显微岩类型与层裂隙分布的关系。
