Abstract

In an opencast mine involving hard rock/deposit excavation, blasting becomes a very important activity. Effective usage of explosive energy to fragment and displace the hard strata results in considerable savings. However, the occurrence of blasts in mines is so rapid that the naked eye cannot detect the process. High-speed videography can provide the progress of blast in millisecond time scale needed to analyze the happenings in the blast. An attempt is made through this paper to present a case study of assessing the performance of blasts based on explosive energy available at different sections of the blasthole and correlating it with burden rock movement.

Keywords: Blast performance, energy distribution, burden rock movement
