摘　　要：对豫北二1煤X射线衍射与构造煤变质进行的研究结果表明 ,构造煤X射线衍射曲线中的 0 0 2衍射峰比原生结构煤的要高且尖 ,d0 0 2 值比原生结构煤的平均要小 0 0 0 6nm ,Lc 平均要大 0 5836nm 。X Ray Diffraction(XRD)of No 2 1 seam coal and dynamometamorphism of fault coal in the north of Henan Province are studied.The result shows that the 002 diffraction peaks of fault coal samples are higher and more narrow than of primary coal samples, the average numerical value of d 002 reduces 0 006 nm and the average numerical value of L c increases 0 583 6 nm.These data reveal that dynamometamorphism has occurred to No 2 1 coal.
