摘　　要：通风网络解算的核心是通风网络解算方法。重点介绍了计算机技术普及前后通风网络解算方法的研究状况及通风网络解算软件的发展情况,通过对比发现:无论采用何种矿井通风网络解算模型,通风网络解算都是大型非线性方程组的解算。在没有计算机的辅助下,通风网络解算只能使用图解法和物理模型方法,只有简单的通风网络可以采用Scott-Hinsley法进行手工解算。通风网络的不同矩阵形式与矿井空气流动规律相结合,形成不同的通风网络解算模型:回路法、节点法和割集法模型。解算非线性方程组的所有方法都可以用于解算这些数学模型。The core of the ventilation network solution is its solution methods. This paper emphatically described the research status of the ventilation network solution methods and the development situation of the ventilation network solution software before and after the popularization of computer technology,it was found out by comparison that no matter what the mine ventilation network solution model was applied,the ventilation network solution was the solution of the large- scale nonlinear equations. Without the aid of the computer,the ventilation network can only be solved with the graphic method and physical model method,and only the simple ventilation network can be manually solved with Scott-Hinsley method. The combination of different matrix forms of the mine ventilation network with flow regularity of the mine air formed different ventilation network solution models,including the loop method,node method and cut set method models. All methods for solving nonlinear equations can be used to solve these mathematical models.
