中文摘要：

以米村矿为例,随着210071工作面的推进,米村矿通风方式由原来的两翼对角式变成中央边界式,所以必须对矿井做通风系统优化调节。以通风阻力测定和主要通风机性能测定为技术手段,掌握通风系统中各部件的性能和功效参数。以此参数为基础,利用河南理工大学开发的VNT 1.0进行了通风网络解算。结果表明：对通风系统优化后,通风系统中各主要参数达到相关规定的要求,保证了通风系统安全、可靠和有效运行。

英文摘要：

With the Micun mine as an example, the ventilation mode of Micun coal mine form two wing oppo- site angle type to central border type as the 210071 working face advancing, and ventilation system optimiza- tion must be optimized. Based on the determination of ventilation resistance and main ventilator performance technology, the main parameters of the ventilation system were investigated. Based on the main parameters, ventilation network optimization by VNT1.0 was published in Henan Polytechnic University. The results show that the main parameters meet the requirements of related regulations after the ventilation system was opti- mized, and that the ventilation system is safe, reliable and efficient to operate.
