摘　　要：随着金属矿山开采深度的增加,高地温越加显现,而矿山在热害控制方面经验不足、个体防护及培训缺失、有效的机械制冷技术应用较少等,亟待加强深井金属矿山热害防治安全技术相关研究。本文分析了深井矿山热环境对作业人员、生产效率的影响,总结了热害防治的综合措施,包括通风系统优化、热源控制、个体防护、压缩空气制冷、机械制冷等方面,列举了南非、澳大利亚两座典型深井矿山机械制冷降温技术的典型应用,供其他深井矿山借鉴。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.
