The aim of this long-term project has been to focus on the extreme high-stress end of the mining spectrum. Such high stress conditions will prevail in certain ultra-deep mining operation of the near future, and are already being experienced in extracting remnants, stabilizing pillars of shaft pillars at more moderate depths. Mining in such ground poses major problems including high rates of closure and ground mobility, difficulties of sitting and support of access tunnels, and above all severely enhanced hazards of rock bursting.
