Network simplification technology on mine ventilation simulation system

通风网络自动简化技术是矿井通风仿真系统的重要组成部分,它是分析矿井通风系统的强有利工具。网络简化对提高与通风网络拓扑关系相关的计算程序的运算速度以及降低计算机内存占有量也具有重要意义。在通风网络风量按需调节通路法、计算机自动识别角联风路等方面都涉及到通路的计算问题,有时风路增加 1 条有可能导致通路总数的成倍增加,所以对通风网络进行自动简化处理具有非常重要的意义。从图论和集合论出发,通过对网络拓扑关系的分析,提出了通风网络简化的数学模型,分析了网络简化的层次性,应用开发的网络简化软件对铁法矿务局大明一矿的通风网络进行了简化处理。

The automatic simplification technology for ventilation network is one of the important members of mine ventilation simulation systems, and it is also a powerful tool to analysis mine ventilation system. Network simplification is significant in enhancing computing speed and reducing memory occupation of programs relative to ventilation network topology relation. Many ventilation network problems, such as the path method of regulation according to the need for ventilation network and the automatic identification of diagonal branches, are related to the computing paths, while sometimes if the branch amount of a network increase by one may lead to fold increase of path amount, so it is important to implement automatic simplification treatment for a given ventilation system. Based on graph theory and set theory, according to the analysis of network topology relation, a mathematical model of ventilation network simplification is put forward, and the hierarchy of network simplification is also analyzed. The developed network simplification software is used on the ventilation network of Daming 1# mine in Tiefa mining bureau.
