| The Multiple Coal-forming Theoretical System and Its Model |
| After a long period of development and with the presentation of various coal-forming theories, the coal geology has entered into a diversified flourishing stage. However, it is necessary to further study such coal-forming theories as coal-forming mechanism during transgression, the influence of plate tectonics on coal-forming during the formation and evolution of basins, the association mechanism of coal and its coexisting and associated minerals and the coal-bearing system theory, which are all closely related to the study of coal-accumulation and unconventional energy resource in the coal-forming basin. The insufficient theoretical study caused by the limitations of every coal-forming theory, however, has affected the prediction and estimation of energy resource. Hence, this paper has presented the multiple coal-forming theoretical system and coal-forming pattern based on systematical and comprehensive understanding of various coal-forming theories. The authors hold that the central idea of this theoretical system lies in the peat accumulation patterns and the water system changes. The interactions between coal-forming multi-factors are illustrated in this theoretical system without explaining each problem separately. The difference of coal-forming system tracts is the main fundamental principle of the supporting framework. There are four basic conditions, namely paleobotany, paleoclimate, paleostructure, and paleoevents (transgression events, tectonic events, volcanic eruption event, etc.). The characteristics of multiple coal accumulation model and different types of coal-forming process as well as mechanism become the main core contents. Four uniformities are emphasized, which are integrity and cooperativeness, originality and convertibility, succession and expansibility, theoretical property and practicalness. On such a basis, the coal-forming mechanism and its relations are explained. It is thus held that the multiple coal-forming theoretical systems include the detailed relations between different factors, the mechanism of dynamic and static conditions, the fusion of different theories, and the coupling principles of many kinds of processes. |
