摘　　要：以煤炭资源调查资料为基础,对西藏东北部地区的煤炭资源赋存状况进行了梳理,统计分析了不同成煤期煤层的煤质分析测试数据,并依据新一轮煤炭资源潜力评价提出的煤炭洁净等级6级划分方案,主要选用灰分、硫分、有害元素(砷、磷、氯)5个评价指标对区内的煤炭资源洁净等级进行了初步划分,并以333+334-1资源量为基础,对不同洁净等级的煤炭资源占比进行了统计分析,早石炭世原煤洁净等级为Ⅲ级,属较好洁净煤,晚二叠世原煤洁净等级为Ⅵ级,属差洁净煤;晚三叠世原煤洁净等级为Ⅳ-Ⅵ级,属中等-差洁净煤。区内以较好洁净煤和差洁净煤为主,占比分别为43.02%、50.17%,中等洁净煤和较差洁净煤较少,合计占比为9.66%。Based on up-to-date coal resources investigation data, combined with previous coal geological results, organized out coal resources hosting situation in the northeastern Tibet. Statistically analyzed coal quality tested data of coal seams from different coal-forming stages, on the basis of renewed coal resources potential assessment suggested coaX cleanliness 6 leveled partition scheme, mainly selected ash, sulfur, harmful element （arsenic, phosphorus, chlorine） contents 5 assessment indices carried out preliminary partition of coal cleanliness grades in the area. Then taking the 333＋334-1 resources as the basis have carried out statistical analysis of different cleanliness coal resource proportions. The early Carboniferous raw coal cleanliness is category III, belongs to better clean coal; late Permian raw coaX cleanliness category VI, belongs to poor clean coal; late Triassic raw coal cleanliness categories IV-VI, belong to medium- poor clean coal. The better clean coal and poor clean coal are the main coals in the area, their proportions are 43.02% and 50.17% respectively; less medium-poor clean coals, totally 9.66%.
