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,隙在不同显微煤煤体布存在较大差异,同时隙布位置与显微煤组合序列有关。

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，以河东煤田北部8＃煤层为例，研究了煤层显微煤与煤层隙布关系。
