Experimental study on controlling road dust raising in the open mine with the YCH dust suppressant

After the road in the test mine was sprayed with dust suppressant,the instantaneous road dust raising concentration behind the running truck,the particle-size distribution,and water content of the road surface dust were measured every day.On the tenth day,the instantaneous road dust raising concentration was 4.9 mg/m³,and the dedusting efficiency was 98.4%.Compared with the measure of spraying water,the measure of spraying dust suppressant on the road not only saved 98% water but also reduced the 31% cost of dedusting.
