Abstract: The load/ storage filling cooling with ice particles is an effective way to solve the problem of thermal damage in deep Wells,but its ice production energy consumption is large and the system operation cost is high. For this reason,Mine Cold Load/ Storage Backfill Cooling System Based on Solar Adsorption Refrigeration was developed. The system consists of surface solar heat collection subsystem,adsorption refrigeration subsystem and underground ice delivery subsystem. Through the establishment of the mathematical model of the subsystem and the TRNSYS model of the ground system,the variation rules of the methanol resolution capacity,adsorption refrigeration capacity and adsorption ice production capacity under the influence of different solar radiation intensity,different seasons and different regions were analyzed respectively,and it was concluded that the solar radiation intensity and solar continuity were the main reasons for the difference of the ice production capacity. Huainan and Nanning regions with superior solar radiation intensity and solar continuity were selected to analyze the ice making energy efficiency of the developed system. The results show that compared with the traditional steam compression refrigeration system, the average energy saving efficiency of the adsorption refrigeration subsystem of the system reaches 64. 71%. The research results show that the research and development of a new mine cooling system combining solar adsorption refrigeration with load/ storage filling cooling is beneficial to efficiently solve the problem of mine thermal damage.
