矿井通风仿真系统双线图的快速自动绘制研究

Research of Rapid and Automatic Rendering of Double-line Graphics of Mine Ventilation Simulation System

矿井通风仿真系统通常采用单线绘制和显示通风系统图,无法反映巷道之间的层位关系。文章创造性地提出了一种新的、效率更高的通风系统双线图的自动绘制方法,即"假双线"法,介绍了"假双线"法的本质与特点、利用"假双线"快速自动绘制通风系统双线图的实现机制、步骤及其实现方法。"假双线"法无需计算双线坐标,可快速实现通风系统双线图的自动绘制,且自动生成的双线图可以正确反映巷道间的层位关系,具有计算量小、执行效率高的特点。

Mine ventilation simulation system usually uses single-line to draw and display ventilation system graphics and can＇t reflect layer relationship among tunnels. The paper put forward a new and highefficient automatic drawing method of double-line graphics for ventilation system creatively, namely ＂virtual double-line＂. It introduced natures and characteristics of the ＂ virtual double-line＂ method,implementation mechanism and steps of rendering ventilation system double-line graphics rapidly and automatically and its implementation method. The ＂ virtual double-line＂ method needn＇t calculate coordinate of the double-line points and can render ventilation system double-line graphics rapidly and automatically, and the double-line graphics can reflect layer relationship among tunnels, which has characteristics of less calculation, high execution efficiency.
