| 中文摘要:通过对中国煤田地质特征的综合分析, 借鉴国外学者对“含煤系统”的界定和划分标志, 运用煤地质学及相关学科等多学科交叉的学术思路和综合的研究方法, 分析了含煤系统的主控因素, 提出了中国含煤系统的研究思路、构成要素, 建立了符合我国煤田地质特色的含煤系统模式, 即提出了含煤系统及其子系统的构成格架。“含煤系统”6个子系统构成, 分别为煤系的地层格架子系统、煤层(群)形态子系统、煤变质及煤类子系统、赋煤区块子系统、煤层气(非常规)成藏子系统、煤系游离气成藏子系统。各子系统间具有密切的成生和制约关系。含煤系统的构建的总体思路是把煤地质学及相关学科的各个分支学科, 以及相关的学科内容置于统一的研究框架之下, 因此含煤系统实际上是组织、集成煤盆地(或煤田)各种地质信息的重要工具, 每个子系统都具有自身特色的、完整的研究内容和分析方法。本文还分析了每个子系统的构成要素。 |

| Abstract:In this paper, research ideas and components of the coal-bearing system in China were put forward, and a coal-bearing system model that fits coalfield characteristics in China was built, which is the main system and whose subsystems have been formed through a comprehensive analysis of the geological characteristics of coalfields in China, in consideration of the definition and division marks of the “coal-bearing system” abroad and by applying the interdisciplinary academic ideas related to coal geology and other relevant disciplines and comprehensive research methods. The “coal-bearing system” is composed of six subsystems, i.e., stratigraphic framework subsystem, coal seam (group) subsystem, coal metamorphism and coal types subsystem, block subsystem, coalbed gas (unconventionality) reservoir subsystem and coal free gas accumulation reservoir subsystem. There exist close genetic and restriction relations between them. The main idea is that each branch and related subject of coal geology are taken under the unified research framework, and the analytical method of the coal-bearing system is also an important tool for organizing and integrating various kinds of geological information concerning coal basin (or coalfield). Every subsystem has its special and integrated research contents and analytical means. In addition, this paper has discussed the primary research contents of the coal-bearing system. |
