Shielding and Robotisation: A New Integrated Concept for Enhancing Safety and Efficiency in Drill-and-Blast Operations
Shielding and robotisation are opening up new perspectives for underground drill-and-blast development. By isolating the high-risk area near the face using a mobile, double-barrier shielding system, the presence of personnel in this zone can be entirely avoided. This shielded system is complemented by an integrated buffer storage unit for the…
