Laboratory study on the dynamic response of rock under blast loading with active confining pressure

With the development of mining shifting to deep underground, the effect of in-situ stress on the stability of deep tunnels cannot be ignored acted upon by dynamic disturbance loads. Numerical simulations of the failure behavior of fissured tunnel model acted upon by the effect of coupled dynamic disturbance loads and in-situ stresses are conducted by using finite difference software AUTODYN. The tunnel model containing a mode I crack was made...
