Discontinuum modelling of blasthole expansion and explosive gas pressurization in jointed media

Recent experimental results indicated that high pressure gases, produced by explosives, play a very significant role in crack development, rock breakage, and subsequent fragmentation and heave. A Discontinuum modelling approach is used in this study to investigate blasthole expansion and gas pressur...
