The options that are open to engineers for cooling mines are limited and are primarily dependent upon the thermophysical properties of coolants. These properties are carefully analysed in the context of cooling mines and a comparison is drawn among Ammonia (R717), Monochlorodifluoromethane' (R22), Dichlorodifluoromethane (R12) and Water (R718). From this comparison the extent of Ammonia's superiority as refrigerant is Evident.
