A mine is an area where humans mine coal resources in a coal-rich mining area. It 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 underground tunnels to 

mine coal, which is an underground coal mine. When the distance between the coal seam and the surface is very close, it is generally 

chosen to directly strip the surface soil layer to excavate the coal, which is an open-pit coal mine. Most of the coal mines in my 

country are underground coal mines. Coal mines include large areas above and below ground and related facilities. A coal mine is a 

reasonable space dug by humans when excavating a geological layer rich in coal, usually including roadways, wells and mining faces. 

         Coal is the most important solid fuel and a kind of combustible organic rock. It is formed by luxuriant plants growing in a certain 

geological age, gradually accumulating into a thick layer in a suitable geological environment, and buried in the bottom of the water 

or in the sediment, and formed by natural coalification in a long geological age. Among the various geological periods in the world, 

the Carboniferous, Permian, Jurassic and Tertiary strata have the most coal production and are important coal-forming times. The 

carbon content of coal is generally 46 to 97%, and it is brown to black with dull to metallic luster. According to the degree of 

coalification, coal can be divided into four categories: peat, lignite, bituminous and anthracite.

         The mine environment requires dust-proof, waterproof, corrosion-resistant and other requirements. For this reason, we have 

developed a variety of safe, waterproof, dust-proof, corrosion-resistant, easy-to-operate and applicable solutions for socket boxes 

and maintenance boxes dedicated to mine projects. Program.
