矿井通风仿真系统双线图的快速自动绘制研究

在深入研究通风网络巷道连接关系的基础上,创造性地提出一种新的效率更高的通风系统双线图的快速自动绘制方法,即"假双线法"。"假双线法"与固定宽度双线法有本质的不同,其本质是将单线巷道的线型用固定宽度双线线型表示,再对交叉点进行消隐处理,无需计算双线坐标来实现双线图的快速自动绘制。该法较好地解决了传统方法的缺陷,具有普遍性,其计算量小,执行效率高,并在双线图的基础上很容易拓展生成通风系统立体图。笔者研究成果,对于研发、改进矿井通风仿真图形系统和解决其他行业类似问题具有一定的参考价值。

Study on the Rapid Automatic Drawing of Double-line Diagram of Mine Ventilation Simulation System

Based on the deep study of the connecting relationship of ventilation tunnels,a more efficient rapid automatic drawing method for the double-line diagram of mine ventilation system,namely,"virtual double-line" method,was creatively presented,which was much different in essence from the method of double-line with fixed width.This method firstly used double-line with fixed width to express the line type of single-line tunnels,and then erased and hided the cross points,thus fulfilled the rapid automatic drawing of double-line diagram without the need of calculating the coordinates of double lines.The method overcome the defects of traditional methods and was of great universality in application;it not only had the characteristics of few calculations and high performing efficiency,but also can be easily developed into the 3-dimentional diagram of ventilation system on the basis of double-line diagram.This study provides reference for improving the mine ventilation simulation system and solving similar problems in other fields.
