Abstract:

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.

Key words:

hand-held X-ray fluorescence analyzer, ore quality testing, roadway sampling
