Abstract: Abstract In rock drilling and blasting, explosion shock waves propagate along the axis of the blasthole as the explosive reaction progresses. Meanwhile, detonation products expand rapidly in the radial direction, resulting ...

Abstract: Abstract Strong blasting disturbance caused by blasting load and high in situ stress is a key problem for weak and broken rock excavation in underground tunnels. Advanced grouting can help control rock blasting damage. ...

Abstract: Blast loads would cause serious damage to concrete gravity dams, and a possible dam break can lead to a catastrophe in downstream populated areas. Preventing damage to dam structures is of great interest in the blast-resistant ...
