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。

The Paleotectonics is the all-important geological factor to control coal-accumulation basin formation and evolution. The Xinjiang coal hosting area is a compound continental block, a mosaic of Precambrian fossil continental plates, micro-landmasses and Paleozoic orogenic belts. During early to middle Jurassic, regional compressive stress relaxed and even regional tensile stress appeared, basin-mountain coupled forelands and craton basins are the principal part of early-middle Jurassic coal-accumulation basins in Xinji-ang. Between two tectonic elements with different basement properties and in orogenic belt interior, have formed zonal faulted depres-sions;in some early stage back-arc basins and residual marine basins distributed areas, inherited subsidence happened and become limnic coal-accumulation basins. In foreland, craton and inherited basins with Precambrian basement have strongest coal-accumula-tion effects;extended faulted depression type intermontane basins developed on Paleozoic orogenic belt have rather large coal-accumu-lation intensity lateral variations.
