Coalfield Structures And Tectonic Coal-controlling Of Anhui Province

Making the geodynamics theory as the guidance and the tectonic coal-controlling as the research core, and through the combination of field investigation and laboratory study, the paper uses various research methods of coalfield structures to carry deep research and systematic summarization on the data available, and summarize the control effect of the tectonism on the whole process of formation, deformation and occurrence of the coal measures. Based on the regional tectonic framework and coalfield structural characteristics, and combining the geotectonic units and coal occurrence units, the division scheme of coal occurrence tectonic units of Anhui province is established; Applicating the tectonic-lithofacies analysis method, subsidence history inversion technique, balanced cross section technique and paleo-tectonic stress field analysis, the formation and evolution process of the coal basins of Anhui province are recovered; Based on the systematicsummarization of the tectonic controlling effect and their defferences of the coal measures occurrence, the classification scheme of coal-controlling structural styles of Anhui province is established according to the geodynamic causes. Integrating the research above, the paper establishes the occurrence state division of the coal deposit of Huaibei and Huainan coalfield, summarizes the accompanying exploration strategies and implemente the guidance of the tectonic coal-controlling to the coalfield geological exploration.
