新疆准东煤田芦草沟煤矿区位于吉木萨尔县北部，矿区含煤面积为272 km2，可采储量约为105×108 t。区内主要可采煤层B1煤层厚度稳定,分布广泛,煤质优良，为准东煤炭主要开采对象。运用煤田地质学、煤岩学的理论和方法，进一步探讨西山窑组巨厚煤层的煤岩学特征和煤相类型。分析结果表明：该煤层显微组分以惰质组为主，镜质组次之，含少量壳质组；煤相类型以干燥森林沼泽相为主，湿地森林沼泽相为辅，泥炭沼泽总体形成于基底沉降速率和泥炭埋藏速率相对较慢，相对弱氧化的还原环境。
新疆準東煤田蘆草溝煤礦區位于吉木薩爾縣北部，礦區含煤麵積為272 km2，可採儲量約為105×108 t。區內主要可採煤層B1煤層厚度穩定,分佈廣汎,煤質優良，為準東煤炭主要開採對象。運用煤田地質學、煤巖學的理論和方法，進一步探討西山窯組巨厚煤層的煤巖學特徵和煤相類型。分析結果錶明：該煤層顯微組分以惰質組為主，鏡質組次之，含少量殼質組；煤相類型以榦燥森林沼澤相為主，濕地森林沼澤相為輔，泥炭沼澤總體形成于基底沉降速率和泥炭埋藏速率相對較慢，相對弱氧化的還原環境。

The Lucaogou prospecting area is located in the northern of the Jimusaer town in Xinjiang,with coal-bearing area of 272 km2 and 10.5 billion tons industrial reserves.The coal-seam B1 was main mineable coal seam with successive and steady distribution and high coal quality.This paper discuss the characteristic of coal petrology and coal facies of coal seam B1 in Xishanyao formation by the theories and methods of the coal geology and coal petrology.The results indi-cat:macerals of the coals was dominant of inertinite,and secondarily vitrinite,with little exinite.Coal facies consist of mainly the dry forest swamp and secondarily of the wet forest swamp,The swamp formed in the environment of relative-ly slow base subsidence and peat bury, and relatively oxidized oxidation-reduction.
