Abstract

Proper FRAGMENTATION is one of the most important objectives of BLASTING OPERATION, achieving this aim mining costs are reduced, considerably. Geo-mechanical parameters have a significant effect on the results of a blast. Available rock mass classifications are generally applicable for stability analysis, design of support system, determination of stand-up time but for BLASTING OPERATION, a comprehensive classification has not been developed.In this research, an attempt has been made to develop a new applicable classification (BRMR) for BLASTING OPERATION by combining RMR and LU-LATHAM classifications with considering the effect of dip and dip direction of joints. Finally, using 3D statistical method and Phosphate Esphordi mine data, a mathematical formula with high correlation was developed between BURDEN, BRMR and FRAGMENTATION indexes (D50, D80).
