Safety, efficiency, innovation – SANDVIK Group technologies in tunnels

Modern tunnel construction requires simultaneously improving safety and work efficiency while mitigating geotechnical and organizational risks. This presentation will outline SANDVIK Group’s approach to comprehensive tunnel construction support—from drilling and excavation, through rock mass stabilization, to the digitization and automation of processes. Modern technological solutions will be discussed, including drilling and data collection systems (e.g., the DTi jumbo) and integrated anchoring and grouting systems that combine several operations into a single work cycle (DSI Hollow Bar System), including the use of resins in challenging geological conditions. The presentation will be enriched with implementation examples demonstrating the real impact of these technologies on safety and work continuity, as well as a discussion of future directions for further digitization and automation at SANDVIK.
