矿井通风中,主要扇风机的特性曲线是反映扇风机的工作状况与矿井风量之间的关系,而矿井通风阻力特性曲线则是反映矿井通风阻力与矿井风量之间的关系。任何一个矿井,为了搞好矿井通风管理工作,都要掌握矿井通风阻力的特性曲线及矿井主要扇风机的特性曲线,这样才能掌握主要扇风机的工作点,了解扇风机的工作状况,即了解
In mine ventilation, the characteristic curve of the main fans reflects the relationship between the working condition of the fans and the air volume of the mine, while the ventilation resistance characteristic curve of the mine reflects the relationship between the mine ventilation resistance and the air volume of the mine. Any mine, in order to do a good job in mine ventilation management, we must grasp the characteristics of mine ventilation resistance curve and the characteristics of the main fan fan shaft, so as to master the main fan operating point, fan fan to understand the working conditions, that is, understanding
