POTVIN, Y.  e  HADJIGEORGIOU, J.. Ground support strategies to control large deformations in mining excavations. J. S. Afr. Inst. Min. Metall. [online]. 2008, vol.108, n.7, pp.397-404. ISSN 2411-9717.

SYNOPSIS Tunnelling under squeezing ground conditions poses significant challenges. There are fundamental differences in the choice of support for mining as opposed to civil engineering. This paper reviews ground support strategies that have been used to control large deformations in mining excavations based on field data from five different mines in Australia and Canada. Recommendations are made for improved ground control strategies in squeezing rock conditions.
