Abstract

Numerical simulation was employed to estimate the dynamic behavior of the canal slope under blasting load based on the blast vibration field test of Yanakandla Mine, Kurnool District of Andhra Pradesh. Blast vibrations were monitored at different distances and based on the data obtained a regression curve was generated. The study consisted of slope stability analysis of the canal near the mine using the Distinct Element Modelling technique in 3DEC software. To simulate the explosion, a simplified triangular blasting load was adopted. The velocity and displacement fields of the slope under blasting were analyzed and the PPV values obtained from numerical modelling showed close approximation to the field investigation results. As a parametric study, a vertical joint was incorporated into the model and analysis was undertaken to determine the influence of joint in the rock mass.

Keywords: numerical simulation, 3DEC, distinct element modelling, triangular blasting load
