Abstract

The dynamic behavior of canal slope under blast load was assessed using numerical modelling approach based on ground vibration samples. Studies were carried out at Yanakandla Mine, Kurnool District of Andhra Pradesh over a period of two months and Blast vibrations were monitored at different distances. Based on the signal processing analysis made, regression based statistical analysis was carried out. In addition, curve fitting analysis made between Peak Particle Velocity of ground vibrations and Scaled Distance resulted in a very good coefficient of determination of about 92% between them. A Distinct Element Modelling technique in 3DEC software was carried out for finding the slope stability analysis of the canal located near the mine by adopting a simplified triangular blasting load. Vertical joint was included in the model and analysis was carried out to determine the influence of joint in the rock mass. It was observed that the Peak Particle Velocity values obtained from numerical modelling are in close approximation to the field investigation results.
