Abstract：X-Ray Diffraction（XRD）of No.21 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 d002 reduces 0.006 nm and the average numerical value of Lc increases 0.583 6 nm.These data reveal that dynamometamorphism has occurred to No.21 coal.
