| Theory and Model of Coal-bearing System |
| 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. |
