To further enhance the wave-cutting efficiency of bubble curtain, a series of field tests were conducted. These tests involved the use of single-tube and multi-row bubble holes, as well as high-speed photography to observe the morphology of the bubble curtain. Additionally, a numerical calculation model for the equivalent thickness of the bubble curtain was constructed using AUTODYN software. The results indicate that the number of bubble hole rows is a critical factor affecting wave-cutting efficiency under the same air flow rate. At a detonation center distance of 12.0 m, the wave-cutting efficiencies for 1, 2, and 3 rows of holes are 89.92%, 97.25%, and 96.41%, respectively. At different distances from the detonation center, the two-row hole bubble curtain demonstrated the highest wave-cutting efficiency, consistently exceeding 95%. The thickness and density of the bubble curtain are maximized for two rows of holes, and the thickness of the bubble curtain is the key factor determining wave-cutting efficiency. The equivalent thickness fitting formula established by combining experiments and simulations has high reliability, and the numerical simulations also exhibit high accuracy. To achieve convenient, efficient and low-cost wave-cutting efficiency, it is recommended that the single-tube two-row hole bubble curtain is applied in similar projects.
