Analysis of the technical scheme of artificial cooling in a deep mining metal mine

According to the actual survey, the temperature of-200 m mining level in a metal mine whose mining depth is about thousand meter has reached 33.95℃, heat disaster in deep wells mining has become the main constraint on safe and effective mining and comprehensive exploitation on deep resources. Because of the ventilation measure taken by the mine at present, its cooling effect is limited. Artificial refrigeration temperature drop measure must be adopted to improve the underground working condition. This paper analyzes the heat resources and their dangers, designs the artificial water cooling and ice-making system on the ground station by theoretically calculating the heat dissipating capacity of the underground heat resources and applying the airconditioning technology in the mine. The cooling system of cold water and ice solution were designed respectively. an economical and technical analysis of the cooling system with the above two cooling sources are also finished. Using ice as a cold source in the deep mine cooling system has already shown its economical and technological advantages. And it is also a development direction of deep mine cooling.
