[0002] Mine exploitation refers to the process of extracting mineral resources from underground or the earth's surface, aiming to obtain metal, non-metallic ore and other resources such as coal, oil and natural gas. This process usually includes multiple stages such as exploration, development, mining and ore processing. In the mining process, the commonly used methods are underground mining and open-pit mining, depending on the depth and geographical conditions of the ore deposit.

[0003] In the prior art, mine exploitation has a greater impact on the environment, so effective environmental management measures need to be taken to reduce its negative impact, including collecting and dust-setting the dust shaken off the surface of the ore during transportation.

[0004] However, in actual use, collecting the dust generated during transportation by the fan often causes the concentrated collected dust to accumulate on the filter screen near the fan, and the water spray dust-setting method still causes the air-borne dust to move towards the filter screen of the fan due to the fixed position of the spray head, which affects the contact area between the air-borne dust and the air, and the dust-setting efficiency of this method is also low. In view of this, we propose an energy-saving and environment-friendly high-efficiency mine exploitation raw material conveying device. SUMMARY
