摘　　要：为了深入了解煤中过渡金属元素的地球化学特征及其对煤成烃的影响,对卧龙湖煤矿二叠系10煤层的23个煤样进行了过渡金属元素含量和灰分产率测试。结果表明:煤中主量过渡金属元素Fe和Ti含量明显较上地壳中元素含量低,微量过渡金属元素中只有Ni和Cu的富集系数大于1,整体上看煤中过渡金属元素含量普遍较低。Co,Ni,Y,Cr,Cu与煤中灰分产率呈正相关,以无机结合状态存在。Cu和Fe的含量与煤层瓦斯含量有一定的相关性,初步认定两者在煤成烃过程中具有催化作用,但需进一步证实。For insight into coal transition metal elements geochemical characteristics and their impacts on hydrocarbon from coal, carried out transition metal elements content and ash yield testing for 23 coal samples from Permian coal seam No.10, Wolonghu coalmine. The result has shown that contents of main transition metal elements Fe and Ti obviously lower than those in upper crust, only concentration coefficient of trace transition metal elements Ni and Cu＆gt;1, on the whole, content of transition metal elements in coal is generally low. Content of Co, Ni, Y, Cr and Cu presents positive correlation with coal ash yield and in inorganic binding state. Content of Cu and Fe has certain dependency with coal seam gas content. Initially determined the two can provide catalysis on coal hydrocarbon formation process, but need to be confirmed.
