摘    要:通过对30件煤样微量元素含量的测定,分煤层、分类型(稀土元素、环境意义微量元素)讨论了煤中微量元素的分布特征。研究发现各样品的稀土元素主要赋存于矿物质中,稀土元素含量均呈正常质量分数水平分布,各煤层的稀土元素分布表现为轻稀土富集、重稀土亏损。受陆源影响的煤,ΣREE含量高,稀土元素主要由陆源物质继承而来。受海水影响的煤,ΣREE含量低,分布模式具有海水性质。形成后受河流冲刷的煤,灰分增加,煤中稀土元素含量增加。该研究成果为煤炭资源的合理开发和利用提供基础资料。

关 键 词:井田  稀土元素  微量元素  环境意义  淮北

Abstract:According to trace element content determination of 30 coal samples,discussed trace element distribution features in coal based on coal seams and element types(REE and environmentally significant elements).The study has found that the REE is mainly hosted in minerals;they are distributed in normal mass fraction levels.The REE distribution in coal seams present as light REE enrichment and heavy REE deficit.Terrestrial impacted coal has higher ΣREE content;they are mainly from terrestrial materials.Sea water impacted coal has lower ΣREE content;their mode of distribution has marine characters.Ash content increasing in fluvial scoured coals after formation,the REE content is also increased.The study results have provided basic information for rational exploitation and utilization of the coal resources.
Keywords:minefield  REE  trace element  environmental significance  Huaibei
