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,隙在不同显类型体中的分布存在较大的差异,同时隙分布的位置与显类型的组合序有。

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，研究了层显类型与层隙分布的系。
