Abstract:
To investigate the types and distribution of coal resources in Northern Qinghai Tibet plateau,the coal geolog- ical background and characteristics of coal resources in Northern Qinghai Tibet plateau were investigated. On the basis of field survey,typical samples test analysis and comprehensive analysis,the main coal area are divided into early Car- boniferous and late Carboniferous,late Permian,late Triassic,early and middle Jurassic. Coal measures are mainly dis- tributed in the Kunlunshan, Jishishan, Tanggulanshan, Tumen-Baqing, Changdu-Mangkang coal belt, etc. The main products related with coal include coal,coal unconventional gas,natural gas hydrate,coal gallium,coal germanium, coal gypsum,coal kaolin and high-quality limestone,etc. Under the action of coal forming environment,coalification and tectonic evolution,Coal-Germanium in coal symbiotic deposit formed in Gama Yangqu region;Coal-coal gas-gas hydrate symbiotic deposit formed in Kaixinling-Wuli region. The formations of T3 bg,P3 n,C1 zd and C2 j all have the po- tential of forming coal-coal gas-coal shale gas hydrate symbiotic deposit.
