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002衍射峰比原生结构煤的要高且尖，d002值比原生结构煤的平均要小0.00 6nm，Lc平均要大0.5836nm，表明构造煤发生了动力变质作用.
對豫北二1煤X射線衍射與構造煤變質進行的研究結果錶明，構造煤X射線衍射麯線中的002衍射峰比原生結構煤的要高且尖，d002值比原生結構煤的平均要小0.00 6nm，Lc平均要大0.5836nm，錶明構造煤髮生瞭動力變質作用.

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.
