矿井通风系统阻力测试与优化研究

Research on Resistance Test and Optimization of Mine Ventilation System

本文以山西某矿地质条件为基础,通过对矿井通风阻力的测量,分析了现有通风系统的状态及问题,提出了三个矿井通风系统优化方案,并选择了最合理的方案并在现场进行了实施。根据优化后的通风系统参数,矿井总风量能够满足井下供风需求,并且总风阻有了明显降低,表明本文优化方案较为合理,能够有效改善通风系统的问题。

Based on the geological conditions of a mine in Shanxi,through measuring the ventilation resistance of the mine,the status and problems of the existing ventilation system were analyzed,and three mine ventilation system optimization plans were proposed,and the most reasonable plan was selected and carried out on site.According to the optimized ventilation system parameters,the total air volume of the mine can meet the demand of underground air supply,and the total air resistance has been significantly reduced.
