Rock-breaking mechanism and experimental analysis
2017-9-1 · When the shock wave in the confined medium with the vicinity of the explosive first impacts on the wall surface of the borehole, the strength of the induced rock shock wave far exceeds the dynamic compressive strength of rock and the borehole surrounding rock is subjected to intensive compressive damage . Hard rock is subjected to crushing damage under high-intensity shock wave while compacting cavity is formed in soft rock.
