| Description |
Though fragmentation is a key issue in opencast blasting and techniques like digital image analysis have been developed for its quick assessment, guidelines are yet to be evolved to improve upon it in various kinds of formations. Step-wise Multiple Linear Regression Analysis of the parameters obtained from 35 blasting events in the overburden benches of three large opencast mines led to ascertain the degree of dominance of various influencing parameters on fragmentation. Guidelines are prepared consequently to suggest the step-by-step remedial measures for improved fragmentation in jointed and massive formations.
