摘要
论文在准格尔煤田的地质背景、煤层、煤质分析的基础上,借助化学分析和X射线粉末衍射分析(XRD)对准格尔煤田高铝煤炭的化学组分和矿物成分进行了测试,并对高铝煤炭氧化铝含量的变化规律进行了研究。研究发现,准格尔煤田煤中的Al2O3来源于含铝矿物高岭石和勃姆石,6号煤层在黑岱沟勘探区煤中Al2O3含量最高,9号煤层在孔兑沟勘探区煤中Al2O3的含量最高。研究还发现,绝大部分矿井的煤中镓元素含量超过了最低工业品位,高铝煤炭的形成与成煤地质条件有关。
Based on the geological background, seam and coal quality analysis of Zhungeer Coalfield, the chemical analysis and the X -ray powder diffraction analysis were applied to the measurement on the chemical components and the mineral compositions of the high alumina coal in Zhungeer Coalfield and to the study on the variation law of the aluminium oxide content in the high alumina coal. The study showed that the aluminum oxide in Zhungeer Coalfield were came from kaolinite and boehmite with aluminium minerals. The aluminium oxide content of the coal in No. 6 Seam of Heidaigou Exploration Area was max and the aluminium oxide content of the coal in No. 9 Seam of Kongduigou Exploration Area was max. The study also showed that the gallium element content of the coal in the major parts of the mine was over the minimum industrial grade and the formation of the high alumina coal was related to the coal formation geological conditions.
