吐哈盆地聚煤构造研究

Study on Coal-accumulating Structure of Turpan-Hami Basin

吐哈盆地侏罗系分布较广,为新疆主要的含煤地层。据前人资料,通过构造演化分析将吐哈盆地聚煤构造划分为石炭—三叠纪聚煤前期、早—中侏罗世聚煤期和中侏罗世末期—新生代聚煤后期等3期构造,总结各期构造对煤田形成、分布、规模、煤层厚度、煤质、煤层缺失、煤层结构、构造及位置变化、煤层保存、开采条件等的影响与控制。

Jurassic in Turpan-Hami Basin is the major coal bearing formation in Xinjiang.After analysis on the tectonic evolution of the Turpan-Hami Basin Coal structure,it was divided into the following three study phases： The early stage of the coal accumulating in Carboniferous and Triassic,coal-accumulating period in the early and middle Jurassic,post coal-accumulating period in the middle Jurassic and Cenozoic,they were constructed to demonstrate structural influence and control to the formation of coal field,distribution,size,seam thickness,coal quality,coal deficiency,,seam structure,structure,position modification,the seams saving,mining conditions
