摘　　要：针对通风机及配套电机在高原地区出现严重降效的问题,从通风动力学原理入手,分析空气物理参数对通风机性能和矿井风阻特性的影响,提出高海拔矿井主要通风机的选型方法及优化设计方案。通过改变通风机的状态参数、同型号风机串联的方法可以提高高原风机的性能。实例表明,经优化设计后的主要通风机应用于高海拔矿井是可行的。该研究为高原低气压、缺氧环境的矿山资源开采提供了技术参考。Aimed at preventing serious efficiency reduction from occurring in the ventilators and nec- essary electromotors used in plateau area, this paper draws on the ventilation dynamics principle and ana- lyzes the effect of physical parameters on ventilator＇ s performance and ventilation resistance characteris- tics and proposes the selection method and optimization design of main ventilator designed for the high al- titude mine. The performance of ventilators tailored for High-altitude mines can be improved by changing the state parameters of the main ventilator and using series connection of the same model ventilator. The practical example shows that main ventilator improved by optimization design promises a feasible applica- tion in high altitude mine. The study may provide a technical reference for mine resources exploitation in low-pressure and oxygen-deficient plateau environment.
