摘    要:应用力化学理论和煤结构分析方法探讨煤的力化学作用机制。认为地质构造水平挤压应力是煤力化学作用的重要能源,其挤压剪切作用,不仅使煤发生变形和破坏,而且使煤结构发生一系列的化学效应,煤结构发生聚合、异构、重排、芳构,形成更大分子网络结构;在短时间内分子断裂、分解形成液态烃(低分子化合物)和气态烃(瓦斯)。这种构造煤是力化学作用的产物。煤力化学作用发生不仅加速煤的变质过程.而且加速烃的转化。有利于低分子化合物和瓦斯的富集。

关 键 词:力化学  构造煤  大分子结构  低分子化合物  瓦斯

Abstract:By the use of mechanochemical theory and coal structure analytical methods, we have discussed coal mechanochemical action mechanism. The horizontal compressive stress is the major energy source of coal mechanochemical actions, its extrusive and shearing actions make coal not only deformation and destruction but also a series of chemical effects on coal structure: aggregation, isomerization, rearrangement, aromatization, and macromolecule net in coal structure is formed; breakage and decomposition of coal molecule bond produces liquid hydrocarbon (low molecular weight compound) and gaseous hydrocarbon (gas). This kind of tectonieally deformed coal is product of mechanochemical action. The coal meehanochemical action not only accelerates coal metamorphism process but also hydrocarbon transformation, in favor of low molecular weight compound and gas enrichment.
Keywords:mechanochemistry  tectonically deformed coal  macromolecular structure  low molecular weight compound  gas
