摘要：

煤是一种对温度、压力等地质环境因素特别敏感的有机岩。煤化作用实质上是煤与外界进行能量和物质交换的一个开放系统。地质历史演化过程中的各种构造热事件必然导致煤发生一系列物理、化学、结构和构造变化,煤中有机组分和无机组分在各种地质营力作用下迁移、分异和改造,从而影响煤层现今赋存状况、煤化程度和煤质特征,在一定程度上记录了沉积盆地动力学过程的地质信息。文中介绍了国内外在煤化作用与构造热事件的耦合效应方面的研究进展,讨论了存在的问题,提出了重点研究课题。

Abstract:

The coal is an organic rock that is very sensitive to geologic conditions, such as temperature and pressure. Coalification process is actually an open system in which coal exchanges energy and materials with the surrounding environment. During the long process of geologic evolution, all types of tectonicthermal activities have occurred and inevitably led to diversification of coal in terms of physics, chemistry, textures and structures. Affected by various geologic agents, the organic matter and the inorganic matter in the coal were moved, differentiated and rebuilt, which influenced the coal seam distribution, coal rank and coal quality, and in some degree recorded a lot of geologic information about the geodynamic process of sedimentary basin. This paper introduces the research advances of coupling effect between coalification and tectonicthermal events at home and abroad, discusses the main scientific problems, and proposes some key research projects for this area.
