Simulation of blast induced crater in jointed rock mass by discontinuous deformation analysis method

Youjun NING, Xinmei AN, Jun YANG, Guowei MA,

Frontiers of Structural and Civil Engineering 2010, Volume 4, Issue 2,   Pages 223-232 doi: 10.1007/s11709-010-0022-5

Abstract: Rock blasting is a dynamic process accompanied with the propagations of shock waves and the dispersionThis paper adopts the discontinuous deformation analysis (DDA) method to simulate the rock blasting processThe blasting process in jointed rock mass is simulated by application of the explosion gas pressure onThe whole process including the explosion gas dispersion, borehole expansion, rock mass failure and cast, and the formation of the final blasting piles in rock blasting are well reproduced numerically.
