Abstract

The purpose of this research is to design blasting pattern and improve the blasting parameters. There are two problems that caused unoptimum blasting result parameters for the III class of development rock mass in the underground gold mine PT CibaliungSumberdaya. First, there is no blasting design specified for the III class of development rock mass. Second, bad implementation of blasthole drilling activity. The actual blasting activity result parameters are unoptimal blasting advance (79,34%), high powder factor/PF (1.43 kg/ton), fine fragmentation (P80 = 20 cm) and high overbreak percentage (33%). The blasting design used for this research was calculated by Jimeno, et al, 1995: 217230. The enhanced parameters are 93.10% blasting advance, 0.81 kg/ton of PF, coarser fragmentation (P80 = 24 cm) and smaller overbreak percentage (8.20%).
