Is it hot underground in Shuanglou Coal Mine in Peixian County?

1, Coal Mine Closed Environment: Shuanglou Coal Mine is a relatively closed environment with poor ventilation and heat accumulation. Common coalbed methane, mechanical equipment, lighting lamps, etc. It will generate heat, which is difficult to dissipate quickly in a closed underground environment, leading to an increase in underground temperature.

2. Heat generated by personnel and equipment activities: In underground coal mines, the activities of workers and the operation of mechanical equipment will generate heat. People's breathing, body temperature and labor activities, as well as the running friction of mechanical equipment, will release heat and further increase the underground temperature.

3. Humidity and moisture: In some coal seam areas, the underground humidity of coal mines is relatively high and the water content is relatively high. The evaporation of water needs heat, and the large underground humidity will reduce the evaporation rate and increase the underground temperature.
