炮掘巷道迎头的棚子加固处理方法

Support Reinforcement near the Working Face of Blast

通过设计一种简易实用的联锁防倒装置 ,解决了工作面迎头棚子在放炮时产生的扭斜、倾倒问题 ,使棚子的整体性、稳定性得到了加强 ,巷道掘进的安全有了保障 ,提高了工作质量和劳动效率 ,经试用效果良好 。

In course of digging mine tunnels,the traditional way to reinforce supports near the working face of blast is unfit for new digging technique. A sort of facility and applied interlock set is designed, the supports wring and fall because of blasting rock are resolved, and the supports whole and stability are strengthened. So safety gets ensured, and work mass and efficiency are improved. The result is good by practise,so it is worthy of using wildly.
