摘　　要：对贵州省主要产煤区的10个煤矿原煤中8种痕量元素的含量进行测定,并与中国煤和世界煤中各相应元素含量进行对比;分析了样品中痕量元素的分布特征,初步探究了产生原因。结果表明,贵州煤对所关注痕量元素的富集程度明显较高,金属矿带对煤中痕量金属元素含量有显著影响。The measurement of 8 kinds of trace elements in raw coal from 10 mines in main coal areas in Guizhou province and the comparisons on these trace elements between the coal of Guizhou province and other parts of the world are conducted. Based on the analysis ot! the distri- bution characteristics of these trace elements, the reasons for the problems are obtained. The study shows that accumulation of the concerned trace elements in Guizhou coal is rather high and the metal belt has sillnificant impact on the content distribution nf trne~ ~]ornont~ in tho rn^l
