Abstract

Controlled blasting techniques are used to control overbreak and to aid in the stability of the remaining rock formation. The less competent the rock mass itself, the more care has to be taken in avoiding damage. Presplitting is one of the most common methods which is used in many open pit minings and surface blast designs. The purpose of presplitting is to form a fracture plane across which the radial cracks from the production blast cannot travel. Presplitting should be thought of as a protective measure to keep the final wall from being damaged by the production blasting. The purpose of this study is to investigate the effect of presplitting on generation of a smooth wall in a rock domain under blast process in continuum rock mess. The 2D distinct element code was used to simulate the presplitting in a rock slope (open pit mining). The blast load history was applied as a function of time to inner wall of each blasthole. Important parameters that were considered in the analysis were stress tensor and fracturing pattern. The blast loading magnitude and blasthole spacing were found to be very significant in the final results.
