复杂通风系统的稳定性分析

Stability analysis of complex ventilation system

对矿井通风系统进行网路风流稳定性分析是保障通风安全的重要措施。文中以通风系统网络解算为工具,建立了网络风流稳定系数矩阵,在此基础上,建立并分别求出网路风流总体稳定性指标、网路风流变化幅度指标和网路变化影响范围指标。通过示例分析,说明了该方法对于通风管理的指导作用。

It is an important method putting up network stability analysis for coal mining ventilation system. As a kind of tools, computer simulation technique was used to set up the coefficient matrix of airway stability. Based on the matrix, the collectivity stability targets, flow variety extent targets and its incidence targets of airways are else founded. From a realistic example analysis, instructive effect was shown when it was used in ventilation supervisal.
