力化学作用与构造煤结构

Mechanochemical Action and Deformed Coal Structure

本文应用力化学理论和煤结构分析方法,研究了煤的力化学作用类型、力化学能量来源及煤结构演化的影响因素,探讨了构造煤形成的力化学作用及其物理—化学动态机制,认为地质构造水平挤压应力是煤力化学作用的重要能量来源,煤体在挤压剪切作用下发生变形、破坏而形成构造煤,另一方面,力化学作用使煤分子结构发生缩聚、降解、芳构、异构和重排等化学变化。指出构造煤是力化学作用的产物,力化学缩聚和降解是构造煤演化的有效作用,构造煤是研究力化学作用机制的良好载体。

In this paper, mechanochemistry theory and coal structure analytical methods were used to study the classification and energy source of coal mechanochemistry, the effects on coal structure evolution, and the mechanzchemical action and physicochemical dynamic mechanism of tectonically deformed coal. The horizontal compressive stress of geological structure is the major energy source of coal mechanochemical actions. The compressive and shearing actions make coal body structure deformed and destructed, thus deformed coal formed. On the other hand, a series of chemical effects occurred in coal molecular structure： polycondensation, degradation, aromatization, isomerization and rearrangement. Deformed coal is the product of coal mechanochemical action, and it is a good carrier for mechanochemical action study.
