摘　　要：青藏高原煤炭资源分布极不均匀,主要集中在青藏高原的北部,以前人研究资料为基础,结合野外实地调查资料,对青藏高原北部的煤系发育状况、分布特征及含煤情况进行了简略分析。青藏高原北部自南向北分为唐古拉山、积石山及昆仑山三个赋煤带,成煤时代从石炭纪、二叠纪、三叠纪到侏罗纪均有分布,且随着含煤时代的逐渐变新各含煤地层的含煤性逐次变差。最终根据以往勘查资料及本次野外调查发现的煤系矿产线索,初步探讨了青藏高原北部地区煤系矿产的工作方向应以稀有元素镓、锗、放射性元素及煤系非常规气资源为主。Coal resources are unevenly distributed in the Qinghai-Tibetan Plateau, mainly concentrated in northern part of the plateau. Based on previous researched data, combined with field investigations have briefly analyzed coal measures development, distribution and coal-bearing status in northern Qinghai-Tibetan Plateau. The north part of the plateau has distributed three coal hosting zones, from southwest to northeast namely Tanggula Mts., Kunlun Mts. and Anyemaqen Mts., coal ages from old to new from Carboniferous, Permian, Triassic to Jurassic and coal-bearing property along with the ages getting poorer successively. Finally based on previous pros-pecting data and this time field investigation found clue of minerals in coal measures, initially discussed the working orientation for min-eral resources in northern Qinghai-Tibetan Plateau coal measures should concentrate on rare elements gallium and germanium, radio-active elements and unconventional gas resources.
