Numerical Investigation of Bench Blasting in Hard–Soft Interbedded Rock Masses: Implications for Blasting Design in Heterogeneous Rock Masses

Uneven energy distribution and suboptimal fragmentation in bench blasting of hard–soft interbedded rock masses are critical challenges in open-pit mining. In this study, a five-hole bench blasting numerical model is developed using the discrete element method (DEM) to systematically investigate the...
