摘　　要：煤矿通风系统对于其安全、高效生产尤为重要,尤其是对于衰老矿井而言,对其通风系统的优化改造势在必行。在对衰老矿井判定标准分析的基础上,对进入衰老期矿井的通风现状进行分析,并针对性提出优化改造方案;采用数值模拟手段对优化改造方案的实施效果进行评估,重点验证优化改造后的风量和风阻两项性能。结果表明,衰老矿井改造后的风量和风阻均达到标准规范要求。The ventilation system of coal mines is particularly important for their safe and efficient production,especially for aging mines,and the optimization of their ventilation system is imperative.Based on the analysis of the criteria for determining aging mines,the current ventilation status of mines entering the aging stage is analyzed and an optimization plan is proposed;the implementation effect of the optimization plan is evaluated by means of numerical simulation,focusing on verifying the performance of both air flow and air resistance after the optimization.The results show that the air volume and wind resistance of the retrofitted aging mine meet the standard specification requirements.
