| 摘 要： | 通过对现场通风阻力测定数据的分析,将矿井通风学伯诺里方程中位能中的Z值,由原定义的测点海拔标高值,修正为测点距通风系统中最低点的垂直距离,消除了原定义所引起的位能计算误差。

| Abstract: | According to the analysis of practical datas in mine ventilation system, the reason of the calculating error that potential energy's Z in Bernaly equation of the mine ventilation theory defined as altitude of measured level is found, therefore Z in this article is amended as vertical distance from measured level to lowest level in the ventilation system, and dispel this calculating error. |
