摘　　要：在一个复杂的地下矿通风网络中,通常存在风阻或风量无法直接通过工程的方法事先测量出来的分支,为复杂通风网络中分支风流特征突然改变的原因推断带来了相当大的困难.为了解决此问题,利用通风系统节点风量平衡定律、回路风压平衡定律和通风系统中其风阻值或风量值可事先测量出来的部分分支的信息,重新构建了通风系统风网解算模型.通过对该模型的严密理论推导,获得了一种新的风网解算方法.该算法还可进行通风系统漏风点辨识.图1,参9.In a complicated underground ventilation network, there are some branches whose airflow volume or airflow resistance cannot be directly measured beforehand by engineering methods so as to bring great ditticulty for deducing the reasons why airflow characteristics of branches are changed suddenly. In order to solve the problem, we apply the law of airflow volume balance of node, the law of the airflow pressure balance of each independent circuit and the information of some branches whose airflow volume and airflow resistance was measured beforehand to reconstruct the network solving model of ventilation system. Through a strictly theoretical deduction, a new general network solving algorithm of ventilation system was obtained. The algorithm can be used to airflow leakaze voints identification of ventilation system.
