Description

Technical Field

[0001] The utility model relates to the field of coal mine tunnel ventilation, and more specifically to an assembled ventilation channel and a coal mine underground ventilation tunnel. Background Art

[0002] In coal mines, ventilation is an important part of coal mine safety. Maintaining air circulation inside coal mines can improve the air quality inside coal mines, reduce the possibility of workers getting sick, and can timely discharge toxic gases inside coal mines, thereby improving the safety of coal mine operations. Ventilation inside coal mines is mainly completed through ventilation tunnels.

[0003] Existing ventilation tunnels in coal mines are mainly assembled by assembled ventilation channels, which can reduce the amount of engineering work during the construction of ventilation tunnels. However, most of the existing assembled ventilation channels are square structures. When the coal mine is deep, the surface of the ventilation channel is subject to greater gravity from the soil, especially the top surface of the ventilation channel. If the coal mine is operated for a long time, it is easy to collapse in the middle of the top surface, thereby causing damage to the ventilation duct, making it impossible to maintain air circulation inside the coal mine, and even causing serious safety accidents.

[0004] Therefore, in view of the above problems, an assembled ventilation passage and an underground ventilation tunnel in a coal mine are proposed. Utility Model Content
