| 中文摘要: |
| 为解决杨村煤矿通风系统出现的北翼采区需风量将大幅增加以及通风阻力大等问题，进行了通风阻力现场测定，找出部分巷道断面小导致通风阻力大以及风机老化等核心问题，并提出四种优化改造方案，利用通风网络结算软件MVENT对四种优化改造方案进行模拟仿真分析比较，得出方案4(扩修-273轨道运输大巷、一采轨道、皮带上山，增加一、三采并联回风巷道并且北翼采区风量向南翼分流，风量为1000m3/min)为最优方案，完全满足安全要求。 |
| 英文摘要: |
| In order to solve the problems of large increase of air demand and ventilation resistance in the north wing of the ventilation system in Yangcun coal mine, the field measurement of ventilation resistance was carried out to find out the core problems such as large resistance caused by small section of some roadways and aging of fans, and four kinds of optimization schemes were put forward. The simulation analysis of four optimization schemes was carried out by using the ventilation network settlement software MVENT By comparison, scheme 4 (expansion and repair of - 273 rail transit main roadway, first mining track, belt climbing, increase of first and third mining parallel return air roadway and air volume of North Wing mining area shunting to south wing, air volume of 1000m3 / min) is the optimal scheme, which fully meets the safety requirements. |
