The video shows bolting a pillar in a underground mine using Sandvik DS411 Robolter. Bolting in underground mining is a process of installing ground support which typically includes mesh and bolts for the safety of people working in an underground environment. This prevents the risk of rock falling on people who are working in an underground environment. It is best practice for safety reasons to always install ground support in an underground environment.
