基于约束最优化的矿井通风系统基础数据组获取方法及其应用

Acquiring Method and Application of Basic Data of Mine Ventilation System Based on Constrained Optimization

对于给定拓扑结构的通风系统,风量和风阻是描述其运行状态的重要基础数据。传统的通风基础数据获取方法具有很大的随意性,要求操作者具备足够的经验。提出"初始网络解算"方法,通过基于约束最优化的风量平衡和风阻平衡2个步骤来获取与实际通风系统尽可能一致的通风基础数据,并对其可能的应用领域进行了探讨。

For a ventilation system with given topological struc- ture, air flow and air resistance are the most important basic data that describe the operation state of the ventilation system. The conventional methods of acquiring basic data of mine ventilation system are very arbitrary and also need enough experience. In the paper,a method named ＂initial network calculation＂ is pres- ented, which is based on constrained optimization and develops two steps of air flow balance and air resistance balance to obtain basic ventilation data matching the objective ventilation system in a great degree. This paper also discusses the possible application area of the obtained ventilation basis data.
