[0029] The mine stacker-reclaimer used in the dome warehouse of the mining area is prone to generate a large amount of coal dust in the coal falling link, and due to the space limitation of the dome warehouse, the dust concentration in the dome warehouse is relatively high. The existence of dust not only pollutes the air of the working environment, but also pollutes the air of the nearby environment. When the dust concentration in the dome warehouse is too high, the dust cannot be timely diffused to the outside of the warehouse with the wind flow, which reduces the visibility in the dome warehouse and causes the visual obstruction of the operating personnel, which is easy to cause misoperation and cause the occurrence of accidental injury accidents of the operating personnel.

[0030] The existing dust suppression measures for the above dust are to separately set up a spraying device in the area outside the stacker-reclaimer, but such a disadvantage is that the water mist is easily affected by the environmental wind flow and cannot fully reach the dust generation area, so the dust suppression effect is poor.
