Abstract: To address dust pollution from haul roads in the Zijinshan Gold-Copper Mine, an environmentally friendly dust suppressant, ZJ801, was developed and tested in an industrial setting. The results show that ZJ801 has aprice advantage over commercially available products. When tailings powder was sprayed with 1 % ZJ801 solution, the moisture volatilization rate after 8 h was significantly better than the rate of 79.28 % under plain water spraying, indi-cating a pronounced moisturizing effect. However, increasing the concentration to 5 % did not significantly enhance the effect. In field trials using ZJ801, concentrations of PM2,, PM,o, and TSP gradually increased 3 days after spraying, with short-term exceedances in PM,,' and PM,o levels observed. Nevertheless, PM,s and PM,o concentrations per 24 h and hourly TSP meet the standards, i.e., the ambient air quality is consistent with the industrial zone standards throughout the 8-day test period after the dust suppressant is sprayed. ZJ801 showed significant suppression of PM,s and PM 10, comparable to the effect of more than 5 water sprayings per day on clear days. Based on these findings, it is recommended that when only water spraying is used, a minimum of 5 applications per day be scheduled between 20:00-06:00 and 12:00-18:00. When using ZJ801, a concentration of 2.5 % is advised, with gradually increasing spraying intervals until a dust suppressant film forms on the surface.
