中文摘要：

基于使用计算机自动绘制矿井通风系统图的需要，利用面向对象的程序设计思想，设计通风系统巷道的自动绘制算法，提出多条巷道连接于一点的处理方法，引入多条巷道在空间交叉的消隐方法。该算法在孔庄矿局部通风系统中进行了应用，结果表明，能一次性、连续、准确、快速地绘制出井下所有的通风巷道。

英文摘要：

Base on the requirement to automatically mapping the mine ventilation system with computer and to utilize design conception of object-oriented programming, an auto mapping roadway method was designed for the mine ventilation system. The paper provided a processing method to have multi mine roadways connected to one point. The paper introduced the hidden-line elimination method for multi mine roadways in space crossing. The calculation method was applied to the local ventilation system in Kongzhuang Mine. The results showed that the auto mapping calculation method can be once, continuously, correctly and rapidly mapping all existing ventilation roadway in the underground mine.
