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,隙在不同显微岩类中分布存在较大差异,同时隙分布位置与显微岩类序列有关。

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.

摘要综利用显微地层学和统计学方法，以河东田中北部8＃层为例，研究了层显微岩类与层隙分布关系。
