Description

Technical Field

[0001] The invention belongs to the technical field of coal mine ventilation, and in particular relates to a coal mine ventilation monitoring device for an industrial environment. Background Art

[0002] Coal became the main energy source in the 18th century Industrial Revolution, and steam trains and steamships began to become the main means of transportation in industrial countries. At the same time, the steel industry also needs a large amount of coal. Urban lighting, heating and cooking also need to use gas. Gas leakage is prone to occur during coal mining, which poses a great hidden danger.

[0003] The existing technology has the following defects:

[0004] 1. When ventilation is performed in existing mine tunnels, fresh air is generally introduced into the mine tunnels through external fans and ventilation ducts. However, due to the excessive length of the ventilation ducts, the wind force gradually decreases in the ducts, resulting in a decrease in the air flow rate entering the interior, affecting the ventilation effect;

[0005] 2. When monitoring air quality in existing mine tunnels, it can only be done at fixed locations, resulting in a small monitoring range for the air, making it difficult to accurately control the air in the mine tunnel;

[0006] 3. Currently, when the air is detected by monitoring sensors, due to the large amount of dust in the mine tunnel, the sensors are often covered with dust, resulting in inaccurate detection data and affecting the monitoring effect.
