多尺度观察和综合分析是煤体变形研究的基本要求。从煤层、手标本和显微尺度上分析了中梁山南矿煤体变形特征。结果表明，区域褶皱作用是控制井田内煤层厚度变化的主要因素，逆断层作用造成局部煤层厚度增大；在宏观和显微尺度上构造煤具有相似的变形特征，表现为随着构造变形程度增强，煤中裂隙的密度加大，粒度变小，煤体强度降低；碎裂煤裂隙表面独特的条纹结构可能是煤体静态剪切破裂的结果，而鳞片煤中大量的摩擦面则是煤体动态剪切变形的产物。

Observation of different scale and comprehensive analysis are basic methods for coal deformation re-search. Examination of coal seams, hand specimens and micro-scale samples reveals the characteristics of coal de-formation in Zhongliangshan southern mine. The results show that the regional fold is the controlling geological factor that affects the thickness variation of coal seam in the mine, and reverse fault has made the thickness of local coal seam increase. The tectonic coal has similar features in macro-and micro-scale. With the increased deforma-tion the density of fractures increases, the size becomes small and the coal strength decreases. The special striated texture of the fractures of cataclastic coal may be resulted from static shear fracturing, while the great amount of friction face of the scaled coal is the product of the dynamic shear deformation of coal.
