高原矿山独头巷道增氧通风数值模拟研究

Study on Oxygen Enhancing Ventilation in Blind Drift at Plateau Mine by Numerical Simulation

以海拔高度为4 200 m的高寒缺氧环境自然条件为依据,对独头巷道增氧通风设计中的相关参数进行了计算。采用CFD方法模拟了供氧浓度为30%~50%条件下独头掘进巷道内增氧通风过程,分析了供氧量与供氧浓度的关系。为高原矿山巷道掘进供氧方案的制定提供了依据。

On the basis of the oxygen lack circumstance of plateau of 4 200 m,the related parameters of oxygen enhancing ventilation desigen of blind drift are calculated.The process of oxygen enhancing ventilation at the condition of 30%~50% concertration of supling oxygen is simulated,and the amount of oxygen and the concentration is analyzed.The result provides data for the plan of enhancing oxygen ventilation in blind drift at plateau mine.
