Abstract:

This paper based on analyzes the theory and control measures of mine heat damage at home and abroad in detail, summarizes the source of heat damage and the control technology of heat damage. The basic mechanism of phase-change cooling of very fine mist is introduced. Numerical simulation of the local spray cooling equipment obtained: 30℃ hot air after cooling equipment into a 20℃~22℃ air flow,and the temperature decreased by 8℃~10℃, in line with the cooling requirements of the mine. So this kind of equipment is promoted the use of study on Green coal mining technology.

Key words: heat damage of mines, phase-change cooling, simulation research
