Description

Technical Field

[0001] The invention relates to the technical field of mining dust removal, in particular to an automatic spray dust removal device for coal mines. Background Art

[0002] As we all know, it is the area where humans mine coal resources in coal-rich mining areas, which is generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig tunnels underground to mine coal, which is an underground coal mine. When the coal seam is very close to the surface, it is generally chosen to directly strip the surface soil layer to mine coal, which is an open-pit coal mine. Most of China's coal mines are underground coal mines. The scope of coal mines includes a large area above and below the ground and related facilities. Coal mines are reasonable spaces excavated by humans when digging geological layers rich in coal, usually including tunnels, shafts, and mining faces. Coal is the most important solid fuel and a type of combustible organic rock. It is formed by lush plants growing in a certain geological age, gradually accumulating into thick layers in a suitable geological environment, and buried in water or mud, and formed by natural coalification over a long geological period; there are many types of coal mining methods, and the coal mining methods used by the world's major coal-producing countries are generally divided into two categories: wall type and column type. These two different types of coal mining methods are very different in terms of coal mining systems and mining processes. According to different mining geological and technical conditions, different coal mining systems and mining processes can be combined to form a variety of coal mining methods. For example, under different geological and technical conditions, longwall mining, pillar mining or other coal mining methods can be used, and longwall and pillar mining methods are very different in terms of coal mining systems and mining processes. Therefore, it can be considered that coal mining methods are composed of two parts: coal mining process and mining tunnel layout.

[0003] During the coal mining process, dust composed of ore particles and other powdery materials will be generated. The large amount of dust generated will cause potential harm to the surrounding environment and human body. Therefore, it cannot be discharged directly into the atmosphere and must undergo dust removal treatment.

[0004] The existing technology usually adopts the method of spray dust reduction to settle the dust generated during coal mining, but the existing spray dust removal device is usually fixed in one direction to spray, and does not have the function of swinging back and forth during the spraying process to improve the dust reduction effect, and the existing spray dust removal device also needs to be improved in portability; therefore, an automated spray dust removal device for coal mines is proposed.
