矿井通风网路的结构可用矿井平面图或其它形式的图表示。美国最常用的两种方法是线条图及示意图。文中介绍另一种形式的图,称为典范图。用典范图表示矿井通风网路的方法诞生于波兰,已广泛流行于欧洲。典范图是表示矿井通风系统的一种不按比例的拓扑图。它简化了矿井通风网路的表述,可区分风流的流向,也可快速进行计算 The structure of the mine ventilation network can be represented in mine floor plan or other forms of diagram. The two most commonly used methods in the United States are line drawings and schematics. The article introduces another form of figure, called the model map. A typical example of a mine ventilation network was born in Poland and has become widely prevalent in Europe. A canonical map is a non-proportional topological representation of a mine ventilation system. It simplifies the expression of the mine ventilation network, distinguishes the flow direction of the wind flow, and allows quick calculation
