Experiment Study on Formula and Field of the Dust Suppressant for the Open Mine Road

Abstract:

Formula and field experiments of road dust suppressant were conducted. The optimal formula of dust suppressant was developed through orthogonal experiment .The moisture content in dust sample sprayed with the dust suppressant was 13.4% after it was left untouched indoor for 21 days. Field experiment was conducted in a big open mine during spring. On the road sprayed with the dust suppressant , the moment dust raising concentration behind the driving truck on the tenth day was 4.9mg/m3 ，lower than post dust concentration required in the national health standard, this shows that the dust suppressant is effective to control road dust raising for 10 days .
