摘　　要：基于神府矿区主采煤层5^(-2)煤层中Mn垂向及平面分布解剖,探讨神府矿区煤中Mn赋存及含量偏高的成因。结果表明Mn含量垂向上表现为波动式变化,与煤相旋回呈现出高度的一致性,即垂向表现为5个波动式旋回,且与煤层灰分产率及硫酸盐硫的变化趋势具有较好的一致性。各井田煤中锰含量等值线呈北东-南西向展布,且Mn含量与Zn含量、A_(ad)、S_(p.d)及煤中的碳酸盐矿物含量之间呈一定的正相关,推测煤中锰元素可能受陆源碎屑物质注入的影响。On the basis of Mn vertical and horizontal distribution analysis in the Yan’an Formation main mineable coal No.5^(-2),Shenfu mining area,has discussed the genesis of coal Mn hosting and content on the high side.The result has shown that the content of Mn vertically presents fluctuating variation,highly consistent with coal facies cycles.That is to say vertically presents 5 fluctuating cycles,and have preferable consistency with coal seam ash content and sulfate sulfur variation trend.Mn content isogram of minefields present NE-SW extension;Mn content and Zn content,A_(ad),S_(p,d) as well as coal carbonate mineral contents present positive correlation.It is inferred that coal Mn possibly impacted by terrigenous clastic debris injection.
