Abstract

Peak particle velocity generated due to cylindrically-charged blastholes fired at different delay detonators in surface blasting can amicably be predicted by an equivalent spherical charge conversion (ESCC) approach wherein the cylindrical charges are replaced by equivalent spherical charges. The validity of this conversion model has been tested through different predictive equations using experimental data of two opencast mines viz. Bhelatand Amalgamated colliery (BAC) and Joribahal Iron Ore Mine (JIOM). Both maximum charge per delay and total charge fired in the round were considered separately. The results show that ESCC approach can be conceptually acceptable and used as a good vibration prediction tool in surface blasting.
