| 摘 要： | 矿井通风系统内巷道的风阻是进行通风管理的重要基本参数。常用的获取风阻的方法是通风阻力测定,而单靠阻力测定获得通风网络中所有分支的风阻是一项艰巨的工作。文中在分析风网风量、风阻、风压关系的基础上,提出了通过测定风量得到部分分支风阻的方法,并实现了计算机的辅助计算。作为一种获得分支风阻的辅助手段,该方法计算简单,精度可靠,减小了测定的工作量,是适于现场应用的一种好方法。

| Abstract: | In a coal mine's ventilation system, the resistance of airway is an important parameter which is helpful to the management of ventilation system. This parameter used to be obtained by the way of surveying in the field, which need great efforts. So it is very difficult to obtain the resistance of every airway. Based on the analysis of the relationship between airflow quantity, resistance and airflow pressure, a new method of calculating a part of airway resistances through the known ones in a ventilation network system is proposed. At the same time, a computer program has been developed to realize the calculation. As an auxiliary method to obtain the resistance of airway, it is a very useful method in the field. |
