Analysis of detonation wave effect in radial water coupling blasting
Published 2024-12-01“…As the water coupling coefficient increases, the pressure on the borehole wall first increases and then decreases, and the energy transfer efficiency first decreases, then increases and then decreases; Due to the presence of water medium, water coupled charge blasting can effectively extend the duration of shock wave action and improve energy transfer efficiency; Compared to the concentric water coupling charge form, the eccentric water coupling charge has a significant eccentric stress field, which can significantly increase the peak pressure of the hole wall on the coupling side, reduce the energy attenuation efficiency, and improve the energy utilization rate. …”
