Numerical investigation on blast-induced rock fragmentation with different stemming structures
Li, Xudong; Liu, Kewei; Sha, Yanyan; Yang, Jiacai; Hong, Zhixian (Peer reviewed; Journal article, 2023-09)Stemming is one of the main concerns in blast of rock engineering due to its impact on explosion energy consumption and rock excavation performance. In this study, blast-induced rock fragmentation under different stemming ... -
Numerical investigation on rock fragmentation under decoupled charge blasting
Li, Xudong; Liu, Kewei; Sha, Yanyan; Yang, Jiacai; Song, Ruitao (Peer reviewed; Journal article, 2023-05)Blasting using decoupled charge is extensively applied in rock excavation and rock fragmentation. In this study, the rock fragmentation induced by blasting using decoupled charge is investigated by combined finite element ...
