摘　　要：分析了金属矿山通风动力系统存在的共性问题,阐述了通风动力系统优化方法。以某大型金属矿山为研究对象,针对其存在的风机与风网不匹配、风机机站不完善等问题,通过分析其原因,提出应用矿用空气幕建立硐室型风机机站的技术措施,并应用矿井通风三维仿真系统软件对技术方案进行模拟、对自然风压进行适时计算,最后确定最佳风机机站位置、风机频率。应用结果表明,在风机装机功率基本不变的情况下,不仅显著增加了矿井的总进风量,使得各中段风量分配合理,而且改善了矿井的通风效果。The existing common problems of ventilation dy- namic system in the metal mine were analyzed and the opti- mization method was elaborated. Taking a large metal mine as the researching object, some problems existed including the mismatch of fans and wind network, as well as the im- perfection of fan station. By analyzing the reasons, the mine- used air curtain to establish fan station of chamber type was proposed as a technical measure. Then, the 3D simulation system of mine ventilation was applied to simulate the meas- ure and calculate the natural wind pressure. Finally, the implement scheme was determined including optimized station place and fan frequency. Results of application indicated that, under a steady power of fan, this measure not only ob- viously raised air volume and achieved a reasonable distribu- tion of air flow for every mid-section, but also enhanced ven- tilation effect of mine.
