古构造是控制聚煤盆地形成与演化的首要地质因素。新疆赋煤区是由前寒武纪形成的大陆古板块、微型陆块与古生代形成的造山带镶嵌而成的复合大陆块体。早-中侏罗世,区域挤压应力松弛甚至出现区域拉张应力,盆-山耦合型前陆-克拉通盆地成为新疆早-中侏罗世聚煤盆地的主体;基底性质不同的两个构造单元之间及造山带内部,形成带状拉张断陷;在某些早期弧后盆地和残留海盆分布的地区,发生继承性沉降,成为陆相聚煤盆地。在具有前寒武纪基底的前陆-克拉通盆地和继承性盆地中,聚煤作用最为强盛;发育在古生代造山带之上的伸展断陷型山间盆地,聚煤强度的横向变化较大。
Paleo-tectonism is the primary geologic factor that controls the formation and evolution of the coal-bearing basin. Xinjiang Fu coal area is formed by the Precambrian continental old plate, micro-block and the Paleozoic orogenic belt inlaid composite continental block. In the early-middle Jurassic, the regional compressive stress was relaxed and even regional tensile stress occurred. The basin-mountain coupling foreland-craton basin became the main body of Xinjiang Early-Middle Jurassic coal accumulation basin. Two structural units with different basement characteristics And within the orogenic belt to form banded stretch faulting. In some areas where early backarc basins and residual basins were distributed, inherited subsidence occurred and became a continental coal-bearing basin. In the Precambrian-based foreland-craton basin and succession basin, the coal accumulation was the most powerful. In the extensional fault-depression mountain basins developed over the Paleozoic orogenic belt, the lateral variation of the coal accumulation intensity was relatively large .
