Based on the environmental background of open pit, and mechanism of dust forming on automobile soil pavement, the selection principle of dust suppressive factors such as adhesion, agglomeration and moisture absorption is established. The dust suppressive factors are selected, and a series of experimental simulations are carried out to test viscosity, hygroscopic capacity, anti-evaporability under a high constant temperature (45℃) and the anti-jarring performance by milling. Further, the industrial application is implemented in both dominant conveyance pavement and ore bunker platform in the open pit. The results show that the dust suppressor, which is composed of dissoluble starch, sodium silicate as well as glycerol, possesses the viscosity of 510mPa·s, the saturated suppressor-absorbing capacity of 64.6% and evaporation rate per unit area of 0.3kg·m~(-2)·h~(-1) under the above temperature as well as lasting anti-evaporation time of 65.17h. It is provided with high performances of adhesive effect, agglomeration, moisture absorption, anti-evaporation as well as road surface solidification. Besides, it has a strong adsorptive capacity, and its effective dust-suppressing time reaches 5 days when the amount of spraying is 0.5~1.0L·m~(-2).
