Abstract:
Through the summary of the coal geological work and achievements in Tibet for nearly 70 years, the current status and main results of coal geological exploration in the main coal mines in the region were reviewed. The formation age, distribution range, coal content and coal quality characteristics of coal-bearing strata in major coal mines in the region were found out. The division of coal-bearing tectonic units and coal-accumulating basins in Tibet was summarized, and the sedimentary systems and sedimentary environments of coal-bearing strata in the main coal-forming periods were preliminarily summarized. It is generally believed that the overall degree of coal geological work in Tibet is not high, and the study of coal action and coal accumulation law needs to be further deepened. The research indicates that the main content of future research is the commonality and difference of residual coal series and surrounding coal-bearing sediments, the temporal and spatial migration characteristics and migration law of coal accumulation, the control and transformation of the evolution of Tethys and the uplift of Qinghai-Tibet plateau for coal-bearing basins, and their influence on the coupled mineralization of various minerals in coal measures so as to provide the basis for the integrated exploration and development of various minerals in the whole region.
