(a) Penetration of the metal jet; (b) propagation of the ballistic wave and shock wave; (c) bubble pulsation. The time t (in milliseconds) is labeled in the bottom right corner, which corresponds to ...
In the process of roadway excavation, it is difficult to effectively control the propagation direction of the surrounding blasthole cracks, and it is impossible to eliminate the damage of the ...
An ideal jet that does not deviate from the charge axis is unrealistic due to manufacturing imperfections and jet fracture. At a large stand-off, the penetration depth of the jet particles that ...
