Description

Technical Field

[0001] The utility model relates to the technical field of coal mine wind windows, in particular to a coal mine safety regulating wind window. Background Art

[0002] A coal mine is an underground or surface mine that mines coal resources. A coal mine is a special type of mine that is mainly used to mine coal, an important fossil fuel that is widely used in power generation, heating, industrial production and other fields. Coal mines usually include two types: underground mines and open-pit mines. Underground mines refer to coal mines located underground. Coal mining is carried out by entering the underground mine through the wellhead, and facilities such as shafts, ramps, and tunnels are needed to transport and lift coal. Underground mines have high safety risks, and safety regulations must be strictly observed and corresponding safety measures must be taken to ensure the safety of miners. Open-pit mines refer to coal mines that are mined on the surface. Open-pit mines use open-pit mining methods to mine coal deposits in the open air through excavation and transportation equipment. They are generally suitable for areas with shallow coal resources. Open-pit mines have the advantages of high mining efficiency and low cost, but they also have a certain degree of impact on the environment and require environmental protection and governance. Existing mine ventilation windows can only be fully opened or fully closed when in use, and the air volume cannot be adjusted and controlled, thereby failing to adjust the ventilation volume. The practicality is poor, which brings inconvenience to users. Utility Model Content
