The vibration propagation and damage distribution characteristics of deep-buried underground cavern blasting

Abstract With the increase of scale an underground cavern, more and towering side walls are left behind by blasting operation, which leaves a huge hidden danger to structure safety cavern. Taking propagation mechanism damage distribution characteristics vibration along elevation direction as research subject, high wall deep-buried cavern can be obtained comprehensive application theoretical analysis, dimensional formula derivation, numerical other methods. Through multiangle comparative internal under effect in caverns is revealed, combined with relationship between surrounding rock velocity, proposed. In addition, through establishment mechanical model response walls, prediction particle velocity condition analyzed, adjusted modified, meet developing requirements control precision.
