    • Abstract
  • In order to completely solve the problem of underground heat damage in Xiaoyun Coal Mine, an underground centralized cooling system was established. Two sets of mine explosion-proof ZLS3300/10000 centralized refrigeration units were designed. The cooling system is compact and can serve two working faces and eight heading faces. After testing, the dry bulb temperature of the two coal mining faces was reduced on average 7.2 °C and 9.25 °C respectively, and the working surface humidity was about 75%. All the indicators met the specified requirements, the working environment has been significantly improved, and the occupational health level and labor efficiency of the mine have been improved.
