The ore body is buried deep down to 1 400 m in a planned large scale gold mine.In that depth,the rock temperature is as high as 42.63 ℃.The heat hazard is serious.So a multi-stage fan station is planned for ventilation to solve the heat hazard in the process of deep mining.A scheme of ground centralized air cooling system and underground centralized water cooling is proposed.The paper in detail introduced the cooling load calculation process,equipment configuration and installed power of the 2 refrigeration and cooling systems,and compared the advantages and disadvantages,and finally chose the underground centralized water cooling system.The plan allows for switch-on ventilation which can start the air cooler according to the mining requirement and control the cooling output,and can reach the goal to save energy and lower consumption.
