Description

Technical Field

[0001] The utility model relates to the field of coal mining, in particular to a ventilation volume regulator for coal mines. Background Art

[0002] Coal mines are areas where humans extract coal resources in coal-rich areas. They are generally divided into underground and open-pit mines. When the coal seam is far from the surface, the coal is usually mined by tunneling underground, which is called an underground coal mine. When the coal seam is close to the surface, the coal is usually mined directly by removing the surface soil layer, which is called an open-pit coal mine. During coal mining, ventilation equipment is required to ventilate the mine.

[0003] Traditional ventilation devices usually use fixed pipes as ventilation devices during the ventilation process. After a long period of ventilation, the ventilation volume cannot be adjusted to achieve more environmentally friendly use, resulting in a certain amount of resource waste. For this reason, the utility model proposes a ventilation volume regulator for coal mines to solve the above problem. Utility Model Content
