摘要(Abstract)：
通过对大别造山带前陆盆地石炭纪含煤岩系高煤级煤的X射线衍射分析 ,探讨了高煤级煤基本结构单元的演化特征及其影响因素。结果表明 ,构造应力作用提高了“煤晶核”BSU的延展度和堆砌度 ,使面网间距减小
Through X ray diffraction(XRD) analysis of high rank Carboniferous period coal located in the northern foreland basin of Dabie Orogenic Belt in the eastern China,the evolution character of XRD parameters of high rank coals and the effecting factors are studied.Tectonic stress result in increasing diameter and the stack height of basic structural unit(BSU),and decreasing the BSU lamellae spacing.
