Empirical approach-based estimation of charge factor and dimensional parameters in underground blasting

Himanshu, Vivek Kumar; Roy, MP; Shankar, Ravi; Mishra, AK; Singh, PK

ABSTRACT:

Underground blasting has many challenges. The primary aim of blast designers is to optimize drilling and blasting parameters to deal with the associated challenges. Optimizing these parameters is currently based on various rules of thumb, which have many site-specific limitations. Accordingly, computation of these parameters using empirical rock fragmentation predictors can be useful for blast designers. This paper presents the results of work on burden-spacing determination by back-calculation from the empirical Kuz-Ram model for underground stope ring blasting.
