【摘要】 矿井通风网络图是矿井通风管理的重要图件之一 ,也是进行矿井通风系统模拟、网络解算、通风系统优化的基础资料 .矿井通风网络图属于图论的范畴 ,是对矿井通风系统的抽象 .本文结合网络图论的有关知识 ,对矿井通风网络图进行了图形和画法分析 ,并进一步指出了矿井通风网络图与矿井通风系统图的区别 ,这对于绘制矿井通风网络图、指导矿井通风管理、确保安全生产具有实际意义更多还原

【Abstract】 The ventilation network graph is one of the important drawings in the ventilation management of the coal mines.It is often used for the simulation,analysis and optimization of the mine ventilation system.The ventilation network graph belongs to the graph theory category,and it is an abstract expression of the ventilation system.According to the graph theory,the ventilation network graph is analyzed from graphics and brushwork.The difference between the system graph and network graph has been pointed out.更多还原
