| 摘 要： | 通过对西藏近70年煤炭地质工作和成果的总结，梳理了全区主要煤矿点的煤炭地质勘查现状和主要成果，基本摸清了全区主要煤矿点含煤地层的形成时代、分布范围、含煤性及煤岩煤质特征；总结了西藏自治区赋煤构造单元和成煤盆地的划分，初步归纳了主要聚煤期含煤地层的沉积体系和沉积环境。总体认为西藏自治区煤炭地质整体工作程度不高，成煤作用和聚煤规律研究有待进一步加深。指出了今后研究的主要内容是总结残留煤系与周边地区含煤沉积之间存在的共性及差异，分析主要聚煤期聚煤作用的时空迁移特征和迁移规律；研究特提斯演化和青藏高原隆起对聚煤盆地的控制和改造作用，分析其对煤系多种矿产耦合成矿的影响，为全区煤系多种矿产的综合勘查和开发提供依据。

Progress and prospects of coal geological work in Tibet |
| |
| 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. |
