Study on Rock Damage Mechanism for Lateral Blasting under High In Situ Stresses

Study on Rock Damage Mechanism for Lateral Blasting under High In Situ Stresses

A 3D numerical model was presented to investigate the blast-induced damage characteristics of highly stressed rock mass. The RHT (Riedel, Hiermaier, and Thoma) model in LS-DYNA was used to simulate the blast-induced damage and its parameters were calibrated by a physical model test. Based on the cal...
