PROBLEM TO BE SOLVED: To effectively prevent dusting during unloading or digging up of dust-prone objects, such as wastes and incineration ash. SOLUTION: This dust dust-proof agent consists of a high-viscosity slurry. In unloading the dust-prone objects 2 raising dust, such as the wastes and incineration ash, from a loading space 1A of a vehicle, such as a dump-track, the discharging of the dust is prevented by spraying the dust discharging preventive agent 6 to the dust discharging objects 2 in the state of being loaded to the loading space 1A of the vehicle or under unloading. In the digging up work of the dust discharging objects discharging the dust, such as the wastes and incineration ash, the discharging of the dust is prevented by spraying the dust discharging preventive agent 6 to the dust discharging objects before or under the digging up work.
