矿井通风基础理论和系统设计中几个问题的探讨

On the Several Issues about the Basic Theory and the System Design of Mine Ventilation

文中探讨矿井通风基础理论与矿井通风系统设计两大类问题.矿井通风理论源于流体力学、热力学等基础理论,但对于它们之间联系的了解却是一个薄弱环节.对矿井通风学与流体力学、热力学等基础理论进行了比照分析,重点剖析了矿井风流流动规律理论分析中遇到的难点,旨在加强矿井通风学与流体力学、热力学等基础理论的联系,以便充分利用相关基础理论的新成果完善和发展矿井通风学,为矿井通风新技术的开发和实践应用服务.关于矿井通风系统设计,结合矿山的地形地貌、矿体赋存状态、矿山开拓、运输、采矿方法和回采顺序等条件,对矿井通风系统和通风方式的合理选择进行分析,提出了设计中应注意的几个问题.

This paper studies the mine ventilation and fluid mechanics,thermodynamics,and other basic theory in order to take full advantage of new results related to the basic theory of improvement and development of mine ventilation science.Several problems on the mine ventilation system and ventilation analysis are discussed combining with mining topography,ore occurrence,mining exploration,transportation,mining methods and recovery sequence of conditions
