摘要
在测定系统阻力的基础上,根据矿井通风系统的实际情况,对矿井通风系统的稳定性进行了分析。以风机的转速、风机的风量、风机的效率三者为切入点,探究大气压力与风机的性能的相关性,提出了矿井通风阻力的实际分布规律,为矿井通风设计、通风系统改造、风压调节和矿井消防提供可靠的理论依据,提出了加强矿井通风系统优化工作,以及改善通风系统工况的相关建议。
Based on the determination of system resistance,the stability of mine ventilation system is analyzed according to the actual situation of mine ventilation system.The speed of the fan,the air volume of the fan and the efficiency of the fan are used as the entry points to explore the correlation between the atmospheric pressure and the performance of the fan.The actual distribution of mine ventilation resistance is proposed,which provides a reliable basis for mine ventilation design,ventilation system modification,air pressure regulation and mine fire fighting.Suggestions related to strengthening the optimization work of mine ventilation system and improving the working conditions of ventilation system are presented.
