An empirical approach of overbreak resistance factor for tunnel blasting

An empirical approach of overbreak resistance factor for tunnel blasting

© 2019 Elsevier Ltd The assessment of overbreak is proposed by means of a novel empirical approach; the ‘overbreak resistance factor’ (ORF), to predict and manage the overbreak phenomenon in tunnel drill-and-blast operations. The proposed ORF is formulated by analysing the relationship between uncon...
