$Influences of the burden on the fracture behaviour of rocks by using electric explosion of wires$

Influences of the burden on the fracture behaviour of rocks by using electric explosion of wires

•An electric explosion method is used for blasting experiments under different burdens.•Crack initiation and propagation under different burdens are observed.•Fracture characteristics within the samples are discussed through simulation. The burden is one of the most important parameters in the blast...
