摘要
为研究淮北矿区芦岭煤矿微量元素地球化学特征,系统采集了芦岭煤矿主采煤层8、9、10煤层各5个原煤样品,采用ICP-MS和ICP-AES测定样品中39种微量元素的含量,分析了不同煤层的元素分布特征,并与华北和中国煤以及地壳中元素含量进行了对比。结果表明:芦岭煤矿山西组煤层煤中微量元素含量要高于下石盒子组煤层;与华北和中国煤中微量元素含量进行比较,芦岭煤矿主采煤层煤中主量元素Fe和微量元素U明显亏损,而微量元素Ga、Li和Pb显著富集;与地壳中元素含量相比,芦岭煤矿煤中亏损型元素较多。
To study trace element geochemical features in the Luling coalmine, Huaibei mining area, has systematically sampled 5 raw coal samples each from main mineable coal Nos. 8, 9 and 10. Through ICP - MS and ICP - AES have tested contents of 39 trace ele- ments in samples; analyzed element distributions in different coal seams ; then carried out comparison of those with North China up to countrywide coals and crust. The result has shown that trace element content in Luling coalmine Shanxi Formation coal is higher than in Xiashihezi Formation coal. Comparing with North China and countrywide coals, the principal element Fe and trace element U are obvi- ously depleted, while trace elements Ga, Li and Pb are obviously enriched. Comparing with crust, Luling coalmine coal has more de- pleted elements.
