Abstract: High temperature and humidity damages were the common problems faced during mine stretch to the deep, which would bring huge harm and effect to the healthy of underground workers and mine safety production. Two major thoughts were discussed of non-artificial refrigeration and cooling and artificial refrigeration and cooling (mine air conditioning cooling) for heat harm control. Main types and basic principle of mine air conditioning cooling were introduced, main technical measures and characteristics were analyzed of non-artificial refrigeration and cooling and the advantages and disadvantages of mine air conditioning cooling scheme.

Key words: Deep mine, Heat harm, Aeration cooling, Air conditioning cooling, Heat and moisture transfer
