respect to rock fragmentation becomes a serious concern because high in-situ stress …

Blasting using decoupled charge is extensively applied in rock excavation and rock
fragmentation. In this study, the rock fragmentation induced by blasting using decoupled …

Backbreak (BB) is one of the serious adverse blasting consequences in open-pit mines,
because it frequently reduces economic benefits and seriously affects the safety of mines …

The conventional blasting rock excavation method is the main means of rock breakage
because of its high productivity, and it is relatively inexpensive compared to other methods …

Decoupled charge structures are widely used in contour blasting because of their lower
peak value and loading rate of the borehole wall pressure (BWP), which plays an important …

Decoupled cylindrical charge structure is widely used in contour blasting to reduce
overbreak and control rock damage, which is critical to the safety and efficiency of rock …

In deep underground mining, the damage evolution and vibration response mechanisms of
rock caused by cut blasting are different from those of shallow rock. It is essential to …

During service life, road tunnels may face threats of accidental explosions, eg, Boiling Liquid
Expansion Vapour Explosions (BLEVEs) due to accidents of vehicles transporting …

When tunnels are excavated in rock masses using the drill-and-blast method, determining
the extent of blast-induced damage is a significant concern for engineers in terms of safety …

The rock drilling and blasting method is the most commonly adopted method for rock
roadway excavation in China, where cutting efficiency is the key factor affecting the …
