Technical Field
[0001] The invention relates to the technical field of unmanned mining of coal mines, and in particular to a device for unmanned mining of dangerous small mine caves in coal mines. Background Art
[0002] Coal mines are 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. This 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. This is an open-pit coal mine. The vast majority of coal mines in my country 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 dug by humans when digging geological layers rich in coal. They usually include tunnels, wells, and mining faces, etc. Coal is the main solid fuel and is a combustible A kind of 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. It is formed by natural coalification over a long geological period. Among all the geological periods in the world, the Carboniferous, Permian, Jurassic and Tertiary strata produce the most coal, which are important coal-forming epochs. The carbon content of coal is generally 46-97%, and it is brown to black with a dull to metallic luster. According to the degree of coalification, coal can be divided into four categories: peat, lignite, bituminous coal and anthracite.
[0003] The existing technology has the following problems:
[0004] 1. In the prior art, there are some relatively small mines when mining in coal mines. If workers mine these mines with narrow entrances, it is inconvenient to crush and mine out large coal blocks in the coal mine layer due to the narrow internal space of the mine. It is also inconvenient to carry large tools, so the coal mines cannot be mined effectively.
[0005] 2. In the prior art, a large amount of smoke and dust is generated during the coal mining process. At the same time, when the drill bit is excavating the coal layer, a large amount of heat is generated due to the long-term friction between the drill bit and the coal layer, which can easily damage the drill bit over time. In addition, the angle of the water nozzle cannot be properly adjusted during the cooling and dust removal process. Therefore, structural innovation is needed to solve specific problems.
