摘要: 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。Abstract: 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 high-efficient 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.
