During the current slope blasting excavation process, it is necessary to consider the impact on the surrounding environment and try to avoid the impact of blasting flying rocks on existing buildings and traffic roads. The traditional conventional blasting flying rock protection method usually uses gunny bags to cover, and at the same time, passive protection nets or retaining structures are set on the slope. However, the protection effect of this method is poor, the influence range of blasting flying rocks cannot be effectively reduced, and the rolling stones along the slope generated by blasting cannot be effectively restricted.
