摘要
从煤地质学和系统论结合的基础上提出含煤系统的概念。含煤系统的基本要素有 :物源、聚煤环境、地下热流。有关的成煤作用包括 :泥炭的原地堆积—异地搬运作用、地壳旋回运动所引起的埋藏作用和成煤阶段的热变质作用。这些基本要素和成煤作用必须在时间空间上相配置 ,才有可能形成有工业价值的煤层。含煤系统在时间上可以分为物质来源子系统、物质堆积子系统、埋藏变质子系统。
The concept of coal system is based on coal geology and the theory of system.Its basic factors are substance sources (plant & peat),coal accumulation environment and underground thermal flow.While its geologic activities include peat accumulation and transportation,embedding activity caused by diastrophism and geothermal metamorphism of coal.The collocation of these basic factors and coal forming activities in time and space allows the formation of valuable coal beds.A coal system can be divided into substance source subsystem,accumulation subsystem and metamorphism system in temporal range.Whereas in special range it may fall into several low class subsystems,resembling with super coal system.
