摘　　要：巴音陶勒盖勘查区位于东胜煤田北部,侏罗系中下统延安组为本区含煤地层,按沉积旋回和岩性组合特征,自上而下可划分为3个岩段4个煤组。以东胜煤田巴音陶勒盖勘查区资料为基础,对勘查区煤层和聚煤环境进行综合研究表明,区内沉积环境以河流—三角洲相为主,伴有滨湖、浅湖和滨湖—泥炭沼泽相,局部发育半深湖相—深湖相。煤层发育严格受沉积环境的控制,区内形成了可对比煤层11层、可采煤层7层。The Bayintaolegai exploration area is situated in the northern part of the Dongsheng Coalfield.The Yan′an Formation of the middle and lower Jurassic is the main coal-bearing strata,according to sedimentary cycles and lithological combinations,it can be divided into three rock segments and four coal formations from top to bottom.Based on the data from the Bayuntaulegai exploration area in Dongsheng Coalfield,a comprehensive study was conducted on the coal seams and coal accumulation environment in the exploration area.It was found that the sedimentary environment in this area is mainly river-delta facies,accompanied by lakeside,shallow lake,and lakeside-peat swamp facies,with locally developed semi deep lake facies-deep lake facies.The development of coal seams was strictly controlled by the sedimentary environment,and this area has formed 11 comparable coal seams and 7 minable coal seams.
