Study on rock crushing effect of uncoupled charge in different media based on numerical simulation
Year: 2025
Type: conference-paper
Abstract: In this paper, based on the finite element numerical simulation, the influence of uncoupled charge on rock blasting effect under the condition of water and air is studied. The results show that the stress wave propagation speed of the air medium uncoupled charge is faster, and the stress fluctuation is larger in the early stage of blasting. The water medium uncoupled charge is more effective in energy transfer and crack formation. This shows that the decoupling charge of water medium can improve the energy utilization rate of explosives, reduce the vibration caused by excessive crushing, save the amount of explosives, and enhance the effect of blasting crushing.
