While these devices can intercept flying rocks to some extent, their buffering effect is limited and cannot effectively reduce the impact and destructive force of flying rocks, thus affecting the safety of blasting operations.

[0004] Therefore, it is necessary to design a buffer device for mining blasting that can provide multiple buffers for flying rocks during blasting operations, reduce the probability of accidents, improve the buffering effect, and enhance the safety of blasting operations. Utility Model Content
