摘　　要：河南荥巩煤田太原组中的风暴异地煤，已全部破碎而完全见不到原生结构、构造；煤因破碎失去光泽而无法划分宏观煤岩类型；煤的显微有机组分破损且凝胶化组分减少、壳质组分增加。煤的灰分产率增高、发热量降低；挥发分产率异常。这些特征不仅与原地生成煤构成了明显对比，而且也揭示了这种异地煤的成因机理。The tempestitic allochthonous coal in Xinggong Coalfield,Henan,no any pri-mary texture and structure can be seen,all in grainsize of silt or clay range because of clasta-tion,and lost its luster,so that unable to define its macrolithotype. Micro organic compo-nent of coal was damaged,gelinite decreased,liptinite increased,ash content increased,calorific value reduced and volatile-matter content anomalous.
