Description

Technical Field

[0001] The invention belongs to the technical field of coal mine dust prevention, and relates to a dust falling, dust receiving and dust guiding experimental system for a hydraulic support of a fully mechanized mining face with a large mining height. Background Art

[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly strip the surface soil layer to mine coal. This is an open-pit coal mine. 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, shafts and mining Excavation face, etc., coal is the most important solid fuel and a kind of combustible organic rock. It is formed by lush plants growing in a certain geological age. In a suitable geological environment, it gradually accumulates into thick layers and is buried under water or in 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 eras. According to the degree of coalification, coal can be divided into four categories: peat, lignite, bituminous coal and anthracite.

[0003] During the coal mining process, the hydraulic supports of large mining height fully mechanized mining faces will generate a lot of dust during operations such as coal cutting and frame moving. At present, the dust removal of a large amount of dust is basically dependent on on-site observation and theoretical analysis. This kind of observation and theoretical analysis method does not have accurate data to express clearly, and it cannot monitor and record in real time. In addition, it cannot achieve the ability of dust falling, dust receiving and dust guiding, which reduces the experimental effect of dust removal of hydraulic supports. Therefore, we provide a dust falling, dust receiving and dust guiding experimental system for hydraulic supports in fully mechanized mining faces with large mining heights. Summary of the invention
