Abstract:With the increase of the mining depth of metal mines, the high ground temperature is becoming more and more serious, However, our mines have insufficient experience in heat hazard control, lack of individual protection and training, and less application of effective mechanical refrigeration technology. Therefore, it is important to strengthen the research on the safety technology of heat damage prevention and control in deep well metal mines. This paper will analyzes the influence of thermal environment on operators and production efficiency in deep mine, summarizes the comprehensive measures for heat hazard prevention and control, including ventilation system optimization, heat source control, individual protection, compressed air refrigeration, mechanical refrigeration, etc., and will lists the typical applications of mechanical refrigeration and cooling technology in two typical deep mine in South Africa and Australia, which can be used as reference for other deep mine.
