摘　　要：为了研究嘎顺矿煤的煤岩学特征,运用煤岩学和统计学分析方法,采用荧光煤岩显微镜测试技术,对采自新疆和什托洛盖煤田嘎顺矿的21个煤样和11个顶底板及夹矸样品进行了分析。结果显示:显微组分以镜质组为主(平均值76.6%),惰质组含量次之(平均值18.84%),壳质组含量最少(平均值2.7%)。煤相参数GI、TPI、VI、GWI值以及TPI-GI和GWI-VI两个煤相图解反映出成煤环境为潮湿的还原环境,同时煤岩组分以及煤相类型均指示煤层形成于湖泊沼泽相。Twenty-one coal samples and eleven parting samples were taken h-om Gashun Coal Mine, Hoxtolgay coalfield, Xinjiang autonomous region, and the samples were analyzed by using optical microscopy. The results show that the dominant macerals are vitrinite （av. 76.6%） with minor amounts of inertinite （av. 18.84%） and low liptinite （av. 2.7%）, along with low content of mineral matters（av. 1.86%）. All GI, TPI, VI, GWI values and two facies diagrams indicate that the main coal facies are in limnic area. Meanwhile, the overall petrographic composition and coal facies types indicate that the coal were developed in a strong wet reducing peat accumulating conditions which were the lacustrine marshes.
