摘　　要：某地下矿为新设计井下矿山,地处柴达木盆地西南缘山前地段,有海拔高、气候高寒、多风少雨、蒸发强、昼夜温差大等气候特点,井下采矿对矿井通风的要求更高,选择合适的通风系统及系统风机,均有利于对矿山建设、生产组织,所以该矿段井下通风系统及风机的选择必须充分论证,谨慎选择。通过验证两翼回风方案吨矿系统通风能耗达到3.22 kW·h,为二级标准,万吨矿石用风系数2.19,高于其余两种通风方式,且在系统检修维护时,井下主要作业区域不受影响。One underground mine is a new designed mine,it located in mountain front lot of the southwest margin of Qaidam Basin,it has the following climate characteristics,such as high altitude,frigid climate,more wind and rainless,strong evaporation,big temperature difference between day and night and so on,so it has more ventilation requirements for underground mining,it is advantageous for mine construction,production organization by selection of proper ventilation system and fans,so selection of ventilation system and fans for the ore block must be well demonstrated and carefully selected.Ventilation energy consumption of the system for per ton ore by two wings air return scheme can reach to 3.22 kW·h,it is the level 2 standard,wind use coefficient of ten-thousand-tonnage ore is 2.19,it is larger than the coefficient by the other two ventilation ways,and the main operation area shall not be affected during overhaul and maintenance.
