Support Reinforcement near the Working Face of Blast

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.
