矿井二期工程建设中通常采用局部通风机对工作面进行压入式通风,但是随着井筒之间的短路贯通,原有的相对独立的系统发生变化,建立临时全风压系统,形成一个井筒进风、一个井筒回风的主贯穿风流已成为可能。根据矿井基本建设的具体情况,利用井下已有的巷道安装使用了井下临时主要通风机,形成了副井——井底车场——风井的全风压通风系统,有效地解决了地面局部通风机压风通风距离长、风筒过井筒影响副井改绞等安装工程,风井临时提升不能关闭井口等困难,实现了井底车场建设施工的安全通风,保证了施工进度,收到了良好的效果。
In the construction of the second phase of the mine, the local ventilator is usually used to press-in the working face. However, with the short-circuit between the wellbores, the existing relatively independent system changes and a temporary full-pressure system is established to form a wellbore Into the wind, a wellbore return air flow through the mainstream has become possible. According to the specific circumstances of mine infrastructure, the use of the mine underground tunnel has been installed and used the temporary main ventilator, the formation of the auxiliary shaft - bottom of the car - air shaft ventilation system, effectively solve the local ventilation of the ground The pressure wind ventilation distance is long, the shaft through the wellbore affect the auxiliary shaft rewinding and other installation projects, the wind shaft temporary lift can not close the wellhead and other difficulties, to achieve the safety and ventilation of the construction of underground parking lot construction, to ensure the construction progress, received a good effect.
