Description

Technical Field

[0001] The utility model relates to the field of coal mining, in particular to a coal mining and coal crushing device. Background Art

[0002] Coal mining refers to the process of separating valuable coal from underground or surface and transporting it away from the site. As one of the main energy sources in my country, coal plays an important role in the development of the national economy. Mining methods are mainly divided into open-pit mining and underground mining, of which underground mining is the more common and complex method.

[0003] Some of the mined coal blocks are large in size, which are inconvenient to transport and store. Therefore, a crusher is needed to break the large coal blocks. However, a large amount of dust will be generated during the crushing process. In order to reduce the generation of dust, water will be sprayed into the material port of the crusher to remove dust. The water will combine with the coal powder to form coal slime and fall back into the coal blocks. During transportation, the water in the coal slime dries up and the dust will float out and pollute the environment. Therefore, a coal mining and coal crushing device is proposed.
