Deep hard rock mining and rock mechanics challenges

Mining at depth is associated with high stress magnitudes and often serious ground control problems. Two different extreme conditions: (a) hard rock and seismic problems, and (b) altered weak ore or weak ore contact zones in a hard host rock mass resulting in large deformations and squeezing conditions, are typical for deep mining in Sweden.
