The effective use of analytical and numerical ground support design tools requires the use of reliable and representative data on the behaviour of ground support under load. In practice, such data are limited and not readily available. This paper reports on the construction of a comprehensive database of in situ rockbolt pull tests conducted in Ontario underground hard rock mines. This database includes tests on the complete range of rockbolts currently used in Ontario mines. The data were further analysed to develop practical guidelines on the pull capacity and deformation characteristics of the tested bolts.
