The utility model relates to a cold vacuum cooling system for a mine vacuum ice making. Cooling towers, chillers, water pumps and cooling water supply and return pipes form cooling water heat discharge circulatory system. Cold water circulation system is formed by water chiller, vacuum ice maker, water pump and chilled water supply and return pipe. A vacuum ice maker, an ice conveying device and a borehole ice conveying pipeline are connected with an underground ice melting tank, and the cold water pump, the cold water supply pipe, the work surface air cooler and the cold water return pipe form a downhole ice melting refrigeration and cooling circulation system. At work, the chiller produces 5 degrees of cold water and is sent to a vacuum ice maker. A small part is made of granulated ice, most of which is 10 degrees centigrade. The water is returned to the chiller and continues to be chilled at 5 degrees centigrade. The granular ice is sent to the underground by the ice conveying device, and the molten ice bath is melted into 3 DEG cold water, and is sent to the air cooler at the working surface to prepare the cold air at 12~18 degrees to the working place to achieve the purpose of cooling down. The water that absorbs heat returns to the pit and melts the ice pool to melt the particles of ice. The utility model has the advantages of simple structure, low cost, stable performance and good cooling effect.
