摘　　要：通过对平顶山、郑州和南票三大矿区石炭二叠纪含煤岩系中高煤级烟煤和无烟煤的显微傅立叶红外光谱分析,探讨了原生结构煤与构造煤的有机大分子结构演化特征及其影响因素。结果表明,构造应力有利于煤中氢发生化学环境转移,使脂肪烃含量相对减少、稳定的芳香烃含量相对增加,促进煤大分子结构缩合度和有序度增加。Through micro-FTIR analysis of bituminous coal and anthracite of Carboniferous-Permian period located in Pingdingshan mine, Zhengzhou mine and Nanpiao mine, the organic molecular characters of deformed coal and undeformed coal and their effecting factors are studied. It is shown that tectonic stress is in favor of the chemistry environment transfer of hydrogen in coal, resulting in the decrease of aliphatic hydrocarbon and the increase of aromatic hydrocarbon in content, and accelerating the polycondensation and ordering of large molecules texture of coal.
