煤矿大坡度长距离斜井盾构法施工独头通风设备选型研究

Study on model selection of ventilation equipment during blind tunneling construction of inclined colliery shaft with long distance and steep slope

结合盾构法施工煤矿大坡度长距离斜井的特点,以及确定的单风管压入式通风系统方案,研究了性能曲线宽广的大风压通风设备选型,并将研究成果应用于示范工程。实践表明,通风系统稳定,通风效果好,为煤矿大坡度长距离斜井盾构安全施工提供了保障。

According to the features of blind tunneling construction of inclined colliery shaft with long distance and steep slope as well as the determined single-duct pressed ventilation system scheme, the paper studied the model selection of large-pressure ventilation equipment with wide performance curve, and applied the study results to example project. Practice showed the ventilation system operated stably with excellent effects. The ventilation system offered guarantee for safe tunneling construction of inclined colliery shaft with long distance and steep slope.
