A study was conducted on a modelling material to assess the influence of various blast design parameters on controlled blasting in quarries. The paper has described the mechanics of controlled blasting and the role played by the decoupled charges in minimizing the generation of fractured rock. It was found that the optimum spacing for controlled blasting is 6-10 times the diameter of the borehole and the peak particle velocity generated by the explosive charge should be higher than the ctitical peak particle velocity. The spacing strongly influences the borehole pressure required for a clean break and the critical peak particle velocity required to generate cracks between two adjacent holes. The borehole pressure required to initiate fragmentation has strong dependence upon the burden distance. |
