摘　　要：该文以沉积学、煤岩学和煤相学理论为指导,运用煤相划分参数分析煤相类型,结合宏观和微观煤岩特征,认为新疆准东煤田东部矿区成煤环境为相对干燥的森林沼泽,根据煤相参数的垂向变化,将研究区划分为3种煤相类型:干燥森林沼泽、湿地森林沼泽Ⅰ和湿地森林沼泽Ⅱ。单层煤沼泽类型一般下部为浅覆水森林沼泽或湿地森林沼泽,向上过渡为干燥森林沼泽,代表泥炭沼泽环境由潮湿逐渐变为干燥,覆水程度逐渐变浅,为全区的煤层对比、聚煤规律的认识等提供了理论依据。Based on the theory ol sedimentology, coal petrology and coal petrography, using the coal lacies classili- cation parameter, coal lacies types have been analyzed. According to coal and rock macroscopic and microscopic characteristics ol coal strata, it is summarized that the coal lorming environment is a relatively dry lorest swamp. According to the vertical coal lacies parameters change, the study area is divided into three types ol coal lacies ： dry lorest swamp, wetland lorest swamp I and wetland lorest swamp Ⅱ. Single coal swamp types are generally lower lor shallow overburden water lorest or swamp wetland lorest swamp transition to dry up the lorest swamp. It represents the peat swamp environment gradually become dry, wet water level becomes shallow gradually. It will provide the theory basis lor coal strata contrast and the recognition ol coal accumulating law.
