Modelling Rock Blasting Considering Explosion …
In rock blasting, rock masses may be fragmented and accelerated under both the effect of the explosion shock waves propagating as stress waves and the expansion of the explosion gas in the rock mass (Bhandari 1977; McHugh 1983).Although the fragmentation of the rock would be largely governed by the initial crack patterns generated by the stress wave loadings, it is also generally acknowledged ...
