Study on the Decoupled Charge Effect in Deep-Hole Cumulative Blasting of Coal Seam
Five models of cumulative blasting are established by using ANSYS/LS-DYNA to study the effect of decoupling coefficient on cumulative blasting to improve coal seam permeability. The formation and migration process of the shaped energy jets with two kinds of decoupling coefficient are compared and an...
