Analysis of The Effect Explosive on Fragmentation
View through CrossRef
Abstract. This study was conducted to determine the amount explosives used and fragmentation resulting from blasting activities using WipFrag Software. Methodology in study is to analyze the fragmentation resulting from blasting activities using WipFrag Software to match the criteria cofferdam material, namely 40-70 cm. Data required are burden, spacing, hole depth, stemming and the amount explosives. Calculation of the actual fragmentation distribution using WipFrag software obtained a chunk size of >70cm based on two geometries applied respectively by 20%and30%. Furthermore, blasting geometryand blastingfragmentation distribution were redesigned to optimize fragmentation according to R. L Ash, C. J. Konya and Kuz-Ram. Based on the results the fragmentation analysis carried out according to Kuz-Ram, blastinggeometry was obtained according to R.L Ash with a burden of 2.7 m, spacing of 3 m, holedepth of 6 m and using explosives of 13.87 kg/hole with PF 0.29. Fragmentation produced from this geometry is with anaverage size of rock fragmentation of 40-70 cm and produces chunks of >70cm of 19.21%. While the blasting geometry according to C.J Konya with a burden of 3.5 m, spacing of 3.8 m, Holedepth of 6 m and explosives of 11.08 kg/hole with PF of 0.14 produces chunks of >70cm of 16.50%.
