摘要
通过对豫西滑动构造区二1煤动力变质作用特征的研究,探讨了构造煤变质成烃作用与煤化进程的应力影响因素。研究结果表明,不同性质的构造应力具有不同的煤化效应;与拉张应力相比,具各向异性的挤压应力,对煤变质程度的增加、煤基本结构单元BSU侧链和官能团的脱落,以及煤层瓦斯的生成,都具有很大的促进作用。
Through the research of stress metamorphism character of coal seam II 1 in Ludian gliding structure, the stress effecting factors of metamorphism and hydrocarbon generation process of tectonic coal are studied. As a result, it is showed that different tectonic stress have different effect on coal evolution. Compared with the tensional stress, compressive stress which has appareant anisotropic characteristics produces more accelerating process for abscission of side chains and functional group of basic structural unit(BSU), increase of coal metamorphic degree and generation of coal seam gas.
