手持式X射线荧光分析仪在某铁矿山井下矿石的质量检测

Quality Detection of Hand-held X-ray Fluorescence Analyzer in Underground Iron Ore

在矿山地质工作过程中,井下矿石品位是区分矿岩、地质圈定、矿石损失贫化等诸多生产环节的重要数据依据,而井下矿石品位数据主要靠化学分析试验获得。介绍了手持式X射线荧光分析仪在某地下铁矿应用的可行性研究情况。结果表明:手持式X荧光分析仪对样品铁品位分析几乎不受干湿影响;井下巷道检测表明,化验值与校正值的总体变化趋势基本一致,但存在较大偏差;井下区分矿岩的准确率达100%,区分效果良好。

In the process of mine geological work,the underground ore grade is an important data ba-sis for distinguishing ore rock,geological delineation,ore loss dilution and many other production links,while the underground ore grade data are mainly obtained by chemical analysis test.The feasibility study situ-ationof the application of hand-held X-ray fluorescence analyzer in an underground iron mine is introduced.The results show that the analysis of iron grade by hand-held X-ray fluorescence analyzer is almost not af-fected by dry and wet.The detection of underground roadway shows that the overall change trend of the test value and the corrected value is basically the same,but there is a large deviation.The accuracy rate of un-derground distinguishing ore rock is 100%,and the distinguishing effect is good.
