摘　　要：中侏罗统西山窑组是吐哈煤田三道岭矿区重要的含煤地层,前人对该区域煤层含气性做了相关研究工作,但对该区域西山窑组煤中微量元素尤其是金属元素富集异常关注不够,为探讨吐哈煤田西山窑组煤富矿元素富集状态,本文对砂墩子井田西山窑组煤层展开微量元素分析测试研究。结果表明:西山窑组煤中金属元素富集状态,Ba、Pb、Mo、V、Ni、Zn处于亏损状态;Co、Be、Ga、W、Li、Cr、Sr、Mn处于正常范围;Cu处于富集状态;4-1煤层Ti处于高度富集状态,1-1煤层Ti处于异常高度富集状态。本研究探讨了吐哈煤田三道岭矿区西山窑组煤伴生金属元素分布规律及赋存特征,总结了Ti处于异常高度富集状态的原因,为吐哈煤田煤伴生矿的成矿规律与找矿研究提供新的思路。The Xishanyao Formation of the Middle Jurassic is an important coal bearing formation in the Sandaoling mining area of the Tuha Coalfield.Previous studies have focused on the gas bearing properties of coal seams in this area,but insufficient attention has been paid to the abnormal enrichment of trace elements,especially metal elements,in the Xishanyao Formation coal.In order to explore the enrichment status of enriched elements in the Xishanyao Formation coal seams of the Tuha Coalfield,this article conducts trace element analysis and testing research on the Xishanyao Formation coal seams of the Shadunzi Coalfield.The results show that the metal elements in the coal of Xishanyao Formation are enriched,while Ba,Pb,Mo,V,Ni,and Zn are in a depleted 4-1 coal seam is highly enriched,while the Ti in the 1-1 coal seam is abnormally highly enriched.This study explores the distribution patterns and occurrence characteristics of associated metal elements instate;Co,Be,Ga,W,Li,Cr,Sr,and Mn are within the normal range;Cu are in an enriched state;The Ti in the Xishanyao Formation coal of the Sandaoling mining area in the Tuha Coalfield.It summarizes the reasons for the abnormally high enrichment of Ti,providing new ideas for the mineralization laws and prospecting research of coal associated deposits in the Tuha Coalfield.
