MASTER'S THESIS Investigation of Borehole Stability in
This thesis has been sponsored by LKAB in Sweden. The whole thesis work has been carried out at Malmberget. It involves the investigation of borehole instability in different ore bodies in the mine and how instabilities are affected by various mining activities as the mining progresses downward are...
