摘　　要：呷村银多金属矿井下通风系统属于高海拔高山采矿通风类型。在当前矿井通风系统现状调查与测定的基础上,分析了通风系统存在的问题,提出了两种可行的高海拔矿山通风系统的改造方案。从技术、经济角度对方案进行了对比,优选出最佳方案,即中央进风两翼回风对角抽压混合式地温预热通风方案,可供类似高海拔矿山通风系统参考。The ventilation system of Gacun Silver Polymetallic Mine belongs to the type of high-altitude mountain mining.Based on the investigation and measurement of the present mine ventilation system,this paper analyzed the existing problems of the ventilation system,put forward two feasible renovation schemes for the ventilation system at high altitude mine,compared the schemes from the technical and economic point of view,and optimized the best scheme,namely,forced-exhaust diagonal ventilation scheme preheating by ground temperature with central intake and two wings return.It can provide a reference for similar ventilation systems at high altitude mines.
