随着煤炭科学技术的发展,采用多台风机的通风系统已有明显增长,尤其是大型矿井、老井挖潜、通风系统改造的矿井应用多台风机通风系统比较广泛。本文介绍了主扇工况分析的数学模型,以弥补图解法的缺点,为计算机图解提供了条件,使主扇工况分析既有图解法的直观性,又有数值法的精确性,为生产矿井的通风技术管理提供了新的技术手段。
With the development of coal science and technology, the ventilation system using multiple turbines has been significantly increased. Especially for large-scale mines and old mines, potential ventilation systems have been used to mine more ventilation systems in mines. This paper introduces the mathematical model of the main fan case analysis to make up for the shortcomings of the graphic method for the computer graphics provide the conditions for the analysis of the main fan operating both the intuitive graphical method, numerical method and the accuracy of the production Mine ventilation technology management provides a new technical means.
