摘　　要：以焦作矿区煤矸石为研究对象,采用X R F、X R D研究了煤矸石的化学组成和矿物组成,用H R-ICP-M S、AF S分析了微量元素的含量。结果表明,煤矸石主要化学成分为SiO2和Al2O3,以及F e2O3、CaO、M gO、N a2O、K2O、Ti2O等,矿物组成为石英、高岭石、白云母、方解石及埃洛石。最后,对焦作矿区煤矸石在制备建筑材料、微量元素利用及农业生产等方面的应用进行了评价。XRF, XRD, HR-ICP-MS and ASF were carried out to analyse the chemical compositions, the mineral components and the trace elements in the coal gangue from Jiaozuo coal mining area, China. The results show that the main chemical compositions of coal gangue are SlO2, A12O3, Fe203, CaO, MgO, Na2O, K2O and TiO2. The mineral components of coal gangue are kaolinite, quartz, muscovite, calcite and halloysite. Finally, the feasibility was evaluated for the preparing construction materials, reclaiming trace elements, preparing fertilizer and land reclamation from coal gangue.
