Strain Field Evolution Characteristics of Free Surface during Crater Blasting in Sandstone under High Stress
Considering the problems related to hard rock blasting under high in-situ stresses at large depths, we conducted crater blasting tests on sandstone specimens under three static load conditions to investigate the strain field evolution of rock blasting under high stress. The digital image correlation...
