中文摘要：

论文针对姚桥煤矿两翼采掘工作向深部延伸及矿井生产区域的集中，生产需风量不断增加，两风井将无法满足生产需要等问题，在该矿通风阻力测定的基础上，利用动态模拟风流MFIRE通风网络技术管理软件对该矿后期通风系统优化后的稳定性进行分析研究，结果表明：改造方案安全可行，对其它类似矿井有一定借鉴作用。

英文摘要：

According to the tow wing mining and excavation operations forward to the deep depth in Yaoqiao Mine and the concentration of the mine production areas, the ventilation volume of the mine production would be continuously increased and the two mine ventilation shafts were hard to meet the mine production requirements and other problems. Base on the measurement of the mine ventilation resistance, the technology and management software of the dynamic simulated air flow MFIRE ventilation network was applied to the analysis and study on the stability of the optimized ventilation system in the later period of the mine. The results showed that the reconstruction plan was safety and feasible and would have certain references to the similar mines.
