Description

Technical Field

[0001] The utility model relates to the technical field of coal mining, and more specifically, to an intelligent underground coal mining and excavation integrated machine. Background Technique

[0002] A coal mine refers to a place rich in coal resources, generally divided into underground coal mines and surface coal mines. When the coal seam is far from the surface, generally choose to dig underground tunnels to extract coal, this is an underground coal mine. When the distance between the coal seam and the surface is very close, generally choose to directly strip the surface soil layer to excavate coal, this is a surface coal mine. Coal is the most important solid fuel and is a kind of combustible organic rock. According to the degree of coalification, it can be divided into four categories: peat, lignite, bituminous coal and anthracite.

[0003] Chinese Patent Authorization Publication No.: CN209115103U, provides an efficient coal mining and excavation machine. This patent pre-drills and breaks the coal mine to be mined, preventing the excavation machine from being unable to continue excavation when encountering hard coal lumps, speeding up the coal mining speed, and greatly improving the coal mining efficiency. When coal mining is carried out, it has a good buffering and shock absorption effect on the internal structure of the excavation machine, well protects the internal structure of the excavation machine, and extends the service life of the excavation machine.

[0004] However, when mining coal in a coal mine shaft, due to a large amount of dust generated during the mining process and the slow wind speed inside the coal mine, it is difficult for the dust to be quickly discharged and remains suspended in the shaft for a long time, seriously affecting the health of the staff. The above patent is not equipped with an effective dust reduction device and cannot meet the actual use requirements. Therefore, the utility model proposes an intelligent underground coal mining and excavation integrated machine to solve the deficiencies in the prior art. Content of the Utility Model
