Numerical study on the behavior of blasting in deep rock masses

•The RHT model was used to simulate the rock material and was calibrated.•The stress initialization was achieved in the first step of the simulation.•In-situ stresses can increase the compressive stress and reduce the tensile stress.•Both the crushed zone and the cracked zone are inhibited by in-sit...
