从收集整理资料入手，系统地分析了协尔苏盆地聚煤环境与构造格架，即协尔苏盆地为晚侏罗世-早白垩世地堑式聚煤盆地；聚煤作用取决于盆地沉积环境与古构造环境；是湖泊淤浅沼泽化环境成煤；盆地垂向沉积序列与盆地构造演化阶段相一致；盆地沉降轴心与沉积中心均显示南北向展布。

Starting from to collect data, systematically analyze the Xie’ersu Basin coal accumulating environment and tectonic framework, Namely, Xie’ersu Basin in Late Jurassic-Early Cretaceous graben coal accumulating basin. Coal accumulation depends on the basin sedimentary environment and paleostructure environment, is lake swamp environment. Vertical sedimentary sequence is consistent with tectonic evolution stage of the basin, the subsidence axis and the sedimentary center showed NS distribution.
