Researching the distribution of mining dust concentration and exploring the relationship between dust concentration and full iron concentration is very important to the further study of full iron distribution.It also HYPERLINK app:ds:relieve%20the%20pressure \t _self relieves the pressure brought by undressed ore yields and can be a good help to the HYPERLINK app:ds:prevention \t prevention of dust.This paper researchs start from dust concentration and full iron concentration. To solve these problems,we detected dust concentration on spot in Meishan Iron Mine by reasonable sampling sites method.
