Technical Field

[0001] The utility model relates to the field of dust reduction in mining areas, in particular to a dust reduction structure for an open-air loading and unloading yard in a mining area. Background Art

[0002] During the vehicle loading and unloading operations at the open-air loading and unloading yard in the mining area, a large amount of dust will float in the air due to ore crushing and vehicle transportation. This dust will cause serious air pollution to the surrounding areas. Workers working in a dusty working environment for a long time will also cause damage to their bodies. At the same time, a large amount of dust cannot meet the country's requirements for environmental protection. Therefore, in order to improve the environment of the mining area, it is necessary to continuously sprinkle water on the site. The method of artificial sprinkling water to reduce dust not only wastes water resources, but also the dust reduction effect is not ideal.
