Ground support guidelines for squeezing rock conditions

In a benchmarking paper published in the SAIIM, Potvin and Hadjigeorgiou (2008) reviewed ground control strategies to manage large deformations in underground hard rock mines. Significant differences were identified in the design and acceptable tolerance between civil and mining engineering practice for squeezing ground conditions. Variations were also noted in ground support strategies between Australian and Canadian mines.
This paper reviews the progress in design methodology and practice since 2008. This includes the availability of more effective deformation monitoring, new design tools, greater access to yielding ground support elements, and better installation practices. An improved understanding of technical and practical issues associated with squeezing rock conditions has led to the development of ground support guidelines for a range of squeezing ground conditions in hard rock mines.
