Influence of blast hole shape and in-situ stress on blast damage evolution in granite by numerical simulation

With the increasing development of deep underground engineering projects, under in-situ stress constraints, tunnel blasting excavation faces significant challenges in crack control. This study aimed to explore crack propagation patterns in rock blasting under varying in-situ stress conditions. Numer...
