Abstract

Underground blasting has many challenges. The primary aim of blast designers is to optimize drilling and blasting pa�rameters to deal with the associated challenges. Optimizing these parameters is currently based on various rules of thumb, which have many site-specific limitations. Accordingly, com�putation of these parameters using empirical rock fragmenta�tion 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.
