摘要
本文利用各种测试方法,对淮南谢桥、新庄孜和张集煤矿采集的不同层位来源的240个煤矸石样品的化学成分、矿物成分和微量元素的进行测试与分析,得出了淮南矿区不同煤矿煤矸石的化学成分特征及其中微量元素的含量变化,评价了煤矸石中有害元素的环境影响作用。结合煤矸石基本特征,提出了合理的资源化利用途径,为煤矿开采过程的主要固体废物煤矸石综合利用和资源化、煤矿环境保护提供了参考资料。
Using various methods tested and analyzed chemical,mineral compositions and trace elements in 240 coal gangue samples from different horizons in the Xieqiao,Xinzhuangzi and Zhangji coalmines,Huainan mining area.The chemical composition characteristics and trace element content variations of gangues in different coalmines in Huainan have been made clear,then the paper evaluated environment impacts from hazardous elements in coal gangue.Combined with the basic features of coal gangue,rational gangue claim and utilization path has been advised,thus provided reference for main solid waste comprehensive utilization and claim,coalmine environment protection during coal mining.
