利用电感耦合等离子体原子发射光谱（ICP-AES）、电感耦合等离子体质谱（ICP-MS）和粉末X射线衍射（XRD）对伊犁盆地48个煤样中常微量元素和矿物含量进行测试，重点探讨As，Cd，Cr，Ni，Pb，Se，Be，Co，Mn，Sb，Th和U等12种潜在有害元素分布及赋存特征。结果表明：①伊犁煤中Mn和Co含量均值接近或超过世界煤和中国煤中Mn和Co含量均值，其他元素均低于世界煤和中国煤含量均值，尤其Se和Cd含量在各样品中均低于检测值；②伊犁煤中Be，Cr，As，Pb，Th和U以铝硅酸盐结合态和碳酸盐岩结合态存在，Mn主要以碳酸盐岩结合态存在，Co和Ni在木斯乡煤中主要以有机结合态存在，在其他伊犁煤中主要以铝硅酸盐结合态存在。

The major,trace elements and minerals of 48 coal samples in Yili basin are determined by using ICP-AES, ICP-MS and XRD.The distribution,mode of occurrence and environmental impact of As, Cd, Cr, Ni, Pb, Se, Be, Co, Mn, Sb, Th and U are discussed in this paper.This paper gives the following conclusions:(1) Compared to the Chinese coal and Worldwide average values of element concentrations,Mn and Co are riched and other elements are depleted in Yili coal, especially Se and Cd that are below the detected limit;(2) Be,Cr,As,Pb,Th and U have aluminosilicate and carbon-ate affinity in Yili coal. Mn is predominantly associated with carbonate minerals in Yili coal.Co and Ni are organically bound in Musixiang coal and are associated with aluminosilicate minerals in other Yili coals.
