Current and historical monitoring data at the Kiirunavaara footwall : a review

• This literature review covers the current and historical surface and underground monitoring systems. Available data from both active and decommissioned systems is collected and presented. The review also covers data retrieved through temporary measurements such as core-drilling, geological mapping and damage mapping. Geotechnical data is sorted by origin and type categorised as rock mass properties, joint set data or equivalent input data for numerical modelling. Measurement data is categorised by origin, observations, field measurements and laboratory data. The results from these geotechnical studies are summarized and referenced to the original publication and put into context to a large scale footwall failure.The study is concluded by a review of some of the previous numerical models covering the Kiirunavaara footwall. The review has found that during the last decade the numerical analyses related to the footwall have all used the same sets of data, all originally compiled and presented in 2001 and that the footwall rock mass has consistently been treated as a single coherent geological unit. Mohr-Coulomb failure models have been used throughout.
