Design tools for squeezing ground conditions in hard rock mines

Abstract: Squeezing ground conditions are encountered in several underground rock mines. This paper addresses the selection of appropriate engineering tools that can be used for the prediction of squeezing and investigates the relative performance of different ground support options. A clear distinction is made between squeezing as a result of weak rock or shear failure and structurally defined buckling failure of the rock mass. A critical assessment is made of available empirical tools with particular emphasis on their… Show more

“…Mercier-Langevin and Hadjigeorgiou (2011) presented a Hard Rock Squeezing Index for underground mines based on case studies from mining operations in Australia and Canada. Hadjigeorgiou and Karampinos (2017) note that this index can provide a first indication for the potential of squeezing and the long-term strain level based on ranges for the foliation spacing and the stress-to-strength ratio.…”

“…This is captured by rock mass classification systems, such as RMR (Bieniawski 1989) and Q (Barton et al 1974) and continuum isotropic numerical models. A critical assessment of the design tools used for the shear failure mechanism has been provided by Hadjigeorgiou and Karampinos (2017).…”
