摘要

Rock blasting has been the popular method for rock breakage in mining and civil engineering. In this paper, laboratory experiments are first carried out in cement mortar samples with various air-decoupled charges to investigate effect of decoupled charge blasting on rock fragmentation efficiency. The geometry of the specimen used in decoupled charge blasting is depicted in Figure 1.
