瓦斯突出隧道的通风设计与运行效果评价

Ventilation Design of Gas Outburst Tunnel and Running Effect Evaluation

结合乌蒙山一号隧道穿越煤层瓦斯的特性,对瓦斯突出隧道施工通风参数选定进行优化,对隧道正洞和平导所需通风量和通风设备选型进行计算,设计采用主扇巷道式通风方案。对通风方案的运行效果进行数值模拟和现场监测,所得结果对其他瓦斯隧道施工通风方案设计具有一定的参考价值。

Combined with the characteristics of Wumengshan Mountain First Tunnel passing through combed gas, the author optimizes the selection of gas outburst tunnel construction ventilation parameter, calculates the ventilation rate and ventilation equipment selection. Main fan roadway style ventilation program is adopted in design. Numerical simulation and site monitor of the running effect of ventilation program are carried out, which is significant for other gas tunnel construction ventilation design.
