通过对准南煤田小西沟矿区钻孔煤心煤样分析，对主要含煤层西山窑组煤岩学、煤相特征、演化规律及控制因素进行探讨，为研究区煤炭资源勘探、开发、煤层对比及聚煤规律分析等提供理论依据。在层序地层分析基础上，运用煤的岩石学、煤化学分析方法，推测研究区西山窑组煤层中显微组分组成以镜质组和惰质组为主，壳质组含量极低。湖扩体系域煤层主要以湿地草本沼泽相为主，高位体系域下部煤层以湿地草本沼泽相为主，上部煤层以潮湿森林沼泽相为主。

Combined with analysis on coal core test results from Xiaoxigou Mine in Southern Junggar Coalfield, this study probed into characteristics of both coal petrology and coal facies, and discussed evolution of Xishanyao Formation and its control factors, which assists in coal seam correlation, coal-forming analysis, and even coal resources exploration and exploitation within target area. Based on relative theories including Coal Petrology and Coal Chemistry, together with sequence stratigraphy, it is concluded that maceral composition of the Xishanyao Formation mainly consists of vi-trinite and inertinite, while liptinite content seems to be extremely low;The coal seams of lake-expension system develop in the wetland herbaceous swamp; and the lower coal seams of high-stand systems form in the wetland herbaceous swamp, while the upper coal seams in the wet forest swamp.
