Background
Hydraulic blasting is a tunnel blasting method which is emerging in recent years, uses water as an intermediate medium to transfer explosion pressure to destroy tunnel rock, and can effectively control air shock waves, flying rocks, noise and the like. The blasting explosive for tunnel blasting is the same as conventional blasting, and the lead wire is led out from the blasthole for placing explosive charges, except that a water bag is filled between the explosive charges in the blasthole, and the outermost water bag is blocked by special stemming. The hydraulic blasting saves explosive quantity, has little influence on environment, has low noise and good controllability and is adopted by more and more blasting projects. However, the water bag adopted by the existing hydraulic blasting is still a common water bag, and the water bag is filled into the blasthole after being filled with water, because the inner wall of the blasthole is uneven and is mostly sharp rock mass, the water bag is easy to be cut, and the outer diameter of the water bag is almost the same as the inner diameter of the blasthole, so the water bag needs to be slowly filled by a small wing when being filled into the blasthole, and the operation efficiency is lower.
