Numerical study on the effect of in-situ stress on smoothwall blasting in deep tunnelling

In the present study, a numerical model is first calibrated against the crack networks and pressure attenuation data in laboratory blasting test. Then, based on the calibrated numerical model, two-hole plane models are developed and used to perform a series of simulations of smoothwall blasting in d...
