本文选择阜新盆地海洲露天矿、山西大同煤田煤峪口矿和朔县平朔煤田安太堡露天矿三种不同类型盆地的矿区进行煤中微量元素的对比研究。初步阐述了断陷盆地、陆表海盆地和大型内陆拗陷盆地煤中的微量元素特征，对比了这三种不同类型盆地煤中微量元素的差异，并提出产生这些差异的主要因素是泥炭沼泽形成时的沉积环境背景、泥炭沼泽相及盆地的物源区。
In this paper, we select the trace elements in coal from three coal mine of Haizhou open-pit mine in Fuxin basin, Meiyukou mine in Datong coalfield of Shanxi province and Antaibao open pit mine of Pingshuo coalfield in Shuo County. The characteristics of trace elements in coal in fault basins, continental seas, and inland depression basins are preliminarily described. The differences of trace elements in coal from these three different types of basins are compared. The main factors that cause these differences are the formation of peat swamps Sedimentary environment background, peat swamp facies and source areas of the basin.
