摘　　要：通过１７件构造煤和４件正常煤系列煤样的Ｘ射线衍射分析，深入探讨了构造煤基本结构单元的演化特征及其影响因素，阐明了构造应力作用是促使煤单元面网间距减小和堆砌度及延展度增大的重要影响因素．构造煤镜质组最大反射率与基本结构单元的演化具有良好的相关关系，是煤田构造研究中进行应力－应变分析的重要标志物之一．The evolution of XRD parameters of high rank tectonic coals and its factors are inquired in depth through analysis of X ray diffraction (XRD) for 17 tectonic coals and 4 normal coals. It is expounded that the tectonic stress might be one of the important factors which result in decreasing the BSU lamallae spacing and increasing the stack height and diameter of basic structural units (BSUs) in the coals. There exists a good interrelationship between the maximum vitrinite reflectance ( R o,max ) and BSU structure of the tectonic coals, so R o,max should be one of the important indicators for the analysis of the stress and strain in the tectonic stress field of coalfield.
