摘　　要：对乌鲁木齐市13个煤矿、22个用煤单位商品燃煤中Hg、As、Pb、Co、Zn、Ni、Cd、Cu和Cr含量,相关性及区域分布特征进行了研究。结果表明,各元素含量均在中国煤各元素含量范围内,Cu和Cr含量算术平均值略高于中国煤中算术平均值,其他微量元素含量算术平均值低于中国煤中算术平均值;各元素含量之间无高度相关,两组元素含量之间显示中度正相关,6组元素含量之间显示低度正相关;南部煤矿Hg和As算术平均值明显高于其他区域,西部煤矿Cd算术平均值明显低于其他区域,各区域各元素含量范围多数差异较大,未显示出区域一致性。The contents of Hg,As,Pb,Co,Zn,Ni,Cd,Cu and Cr in commercial coal,correlation between the elements and regional distribution of 13 coal mines,22 coal-fired enterprises from Urumqi were analyzed in this work. The results showed that the content of each element within the scope of chinese coal,the arithmetic mean of Cu,Cr were slightly higher than the arithmetic mean of chinese coal,the arithmetic mean of other trace elements were lower than the arithmetic mean of chinese coal. There wasn’ t a strong positive correlation between the elements,two groups of elements showed moderate positive correlation,six groups of elements showed low positive correlation. The arithmetic mean of Hg,as in the southern mines were significantly higher than other regions. The arithmetic mean of Cd in western mines were significantly lower than other regions,the content range of most elements in most regions was different and did not show regional coherence.
