microlithotype

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,裂隙在不同显微岩类型体中存在较大差异,同时裂隙位置与显微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统计方法，以河东田中北部8＃为例，研究了显微岩类型与裂隙关系。
