| 摘 要： | 提出了“封闭性网络”的概念,分析了封闭型网络的形成原因及其合理性;与含自由风路的风网对照,说明了封闭型网络可导致矿井出现附加阻力、增加矿井总阻力的弊端.基于最长路算法原理,说明了附加阻力的计算方法.实现了以确定自由分支和加边法找独立回路为内容的封闭型网络解除方法.以某矿通风系统优化为例说明了封闭型网络的具体表现与相关方法的优越之处.

| Abstract: | The concept of closed ventilation network is put forward,and the reason and rationality of its formation are analyzed.Compared with the ventilation network including a free air route,a closed ventilation network can result in additional resistance and raising the total resistance of the mine.Based on the theory of longest route method,a computational method for additional resistance calculation is explained.A solving method of closed ventilation networks is realized based on free branch recognition and adjo... |
