摘要： 煤炭作为一次能源的一种，对其勘查尤为重要。以宁缠矿区为研究对象，对青海省石炭系海陆交互相成煤环
境进行典型矿床研究。从区域地质、矿区地质、煤层和煤质特征4 个方面进行分析，并总结了聚煤规律和构造控煤分析
方面的内容，进行了找矿远景分析，为煤炭资源勘查提供可借鉴经验及指导。

Abstract: As a kind of primary energy, coal is particularly important for its exploration. Taking the Ningzhan mining area as the
research object, a typical ore deposit study was carried out on the coal-forming environment of the Carboniferous sea and land in
Qinghai Province. This paper analyzed the four aspects of regional geology, mining area geology, coal seam and coal quality
characteristics, summarized the coal accumulation law and structural coal control analysis, and carried out prospect analysis of
prospecting, providing useful experience and guidance for coal resource exploration.

Key words: Carboniferous; sea-land alternate facies; coal-forming environment; typical deposits; Ningchan mining area
