microlithotype

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学和统计学方法，以河东煤田中北部8＃煤，研究了煤显微煤岩类型煤隙分布的关系。

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,隙在不同显微煤岩类型煤体中的分布存在较大的差异,同时隙分布的位置显微煤岩类型的组合序列有关。
