ABSTRACT

As more and more near surface deposits are mined out, deeper mines are required in order to continue the exploitation of resources. This inevitably leads to the occurrence of more rock bursting, deformation problems and safety issues. Rock burst means stress induced loosening of parts of the rock mass under enormous energy release. It seems to be similar to damage from natural seismic phenomena. Rock burst events occur mostly in deep tunnels and mines but also in regions with high horizontal stresses.
