摘　　要：聚焦于煤矿通风系统的风流稳定性分析,深入探讨了影响风流稳定性的多种因素及其作用机制。采用数学模型构建与实证分析相结合的方法,系统评估了通风网络中各分支的风流稳定性,揭示了风阻变化对风量分布的具体影响。通风网络中分支的风流稳定性与其对风阻变化的敏感度密切相关,表现为风量变化比例的显著差异。针对风流稳定性较差的通风系统,提出了优化建议,旨在提升通风系统的整体效能和安全性,为煤矿的安全生产与高效作业提供有力保障。Focusing on the analysis of airflow stability in coal mine ventilation systems,various factors and their mechanisms that affect airflow stability were deeply explored.By combining mathematical model construction with empirical analysis,the stability of airflow in each branch of the ventilation network was systematically evaluated,revealing the specific impact of changes in wind resistance on airflow distribution.The stability of airflow in the branches of a ventilation network is closely related to its sensitivity to changes in wind resistance,manifested by significant differences in the proportion of airflow changes.Optimization suggestions were proposed for ventilation systems with poor airflow stability,aiming to improve the overall efficiency and safety of the ventilation system,and provide strong guarantees for the safe production and efficient operation of coal mines.
