摘　　要：新疆卡姆斯特调查区煤炭资源储量丰富,在总结调查区1∶5万煤田地质填图工作基础上,结合区域地质及钻探资料,对该区含煤地层特征及成煤沉积环境进行研究。区内含煤地层主要为早、中侏罗世八道湾组和西山窑组,沉积环境以辫状河-辫状河三角洲-浅湖相为主。全区可采煤层为西山窑组B1煤层,发育于辫状河三角洲平原,该组地层含煤性较好,煤层厚且稳定。The storage volume classification of coal resources in Kamustte investigation area is rich, but the degree of coal geology works which can＇t adapt to the develop of multi-metallic minerals in Altay？Prefecture.This paper analyzes and discusses the problems concerning coal bearing formation in this area and coal-forming environments based on the works of 1 ： 50000 coalfields geological mapping in Kamustte investigation area in Xinjiang, and combined with geology and drilling reference.It is considered that most of the coal bearing formation in the investigation area are early and the medieval Jurassic Badaowan Formation and Xishanyao Formation,and the depositional environment are mainly braid river, braid river deltaand shallow lacustrine sedimentary system. The coal？bearing？formation？that can be dug is B 1 coal seam of Xishanyao Formation, which is developed from braid river deltaand plane. In this formation,coal？ bearing？ property？is fine,and the coal seam is thick and steady.The study result supply the geology basis for the further coal resource development in this area.
