煤岩石学
煤岩学

In accordance with coal sample observation by scanning electron microscope ( sem ) and researches based on such subjects as anthracology , tectonic geology and material mechanics , the endokinetic fractures in coal are further classified into dewatering fractures , condense fractures and static pressure fractures , while the exogenetic fractures are further divided into tensile fractures , pressure fractures , shrink fractures and slack fractures , consistent with the development regularity of the geometric shapes , sizes and arrangement of fractures
摘要分析、归纳了大量的扫描电子显微镜观测结果，以煤岩学、构造地质学研究?基拙，依锯煤中显微裂隙的形态、大小、排列组合等发育特征，将内生裂隙进一步划分?失水裂隙、缩聚裂隙、静压裂隙，将外生裂隙进一步划分?张性裂隙、压性裂隙、剪性裂隙、松弛裂隙。
