Background
Coal mines are areas where humans mine coal resources in coal-rich mining areas, and are generally divided into underground coal mines and opencast coal mines. When the coal seam is far from the ground surface, a tunnel is usually dug to the underground, so that the coal is a mineworker coal mine. When the coal seam is very close to the earth surface, the coal is generally excavated by directly stripping the earth surface, which is an open pit coal mine. The vast majority of coal mines in China belong to underground coal mines. Coal mines, which are reasonable spaces excavated by humans when excavating coal-rich geological formations, typically include roadways, wells, and mining surfaces, among other things, range from above ground to below ground and related facilities. Coal is the most main solid fuel, is one kind of combustible organic rock, and the coal mining needs to use to the blast pipe, the blast pipe is the ventilation of industry and civil building and the metal or non-metal pipeline for air conditioning engineering, it is an infrastructure for making the air circulate, reduce the concentration of harmful gas, and need to use the connector of the pipeline at first;
and the existing air supply pipeline connector is complicated in the mounting and dismounting process and slow in the mounting process, so that the working time of workers is easily reduced.
