摘　　要：针对某矿爆破掘进巷道正头风筒容易受到破坏导致通风效率下降的问题,设计了风筒保护装置,并进行了应用。实践证明,该装置具有成本低、适用性强和保护效果好等优点,可大大减少风筒受损和更换风筒的频次,提高正头风流的稳定性,预计1407工作面全年可节省费用近30万元,具有较好的经济效益和安全效益,可在相同条件工作面和矿井进行推广。In view of the problem that the air duct at the front end of the tunnel is easily damaged and the ventilation efficiency is reduced, the air duct protection device is designed and applied. Practice has proved that the device has the advantages rates of low cost, strong applicability and good protection effect, which can greatly reduce the damage and replacement of the tuyere, improve the stability of the air flow. It is estimated that 1407 working face can save nearly 300000 yuan in the whole year, which has better economic and safety benefits, and can be popularized in the same conditions working face and mine.
