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,隙在不显微煤岩类型煤体中存在较大,时隙位置与显微煤岩类型组合序列有关。

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，以河东煤田中北部8＃煤层为例，研究了煤层显微煤岩类型与煤层隙关系。
