1. Evaluation of structurally controlled rockfall hazard for underground excavations in seismically active areas of the Kiirunavaara mine
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : Sublevel caving operations at great depths are subjected both to large stress concentrations that are redistributed as the mining front progresses and to mining-induced seismicity. This is the case for Kiirunavaara mine, Sweden’s largest underground mine. READ MORE

2. IoT - based Microseismic Detector
University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknikAbstract : Rockfall, which is the detachment of rocks from a mountain, is a major hazard in the mining industry. To help combat this issue, this thesis aims to develop a sensor platform that is able to detect both the potential risk for rockfall and if any rocks do hit the ground. READ MORE

3. Methods for rockfall risk assessment and estimation of runout zones: A case study in Gothenburg, SW Sweden
University essay from Lunds universitet/Geologiska institutionenAbstract : Rockfalls occur around Sweden every year and the country lacks a national risk evaluation and an adequate regulatory framework for construction related to this natural hazard. The aim of this study is to address this problem by mapping areas under possible threat of rockfalls, considering two fundamental aspects: i) identification of the source areas and ii) estimation of the runout zones.

4. Evaluation of the rock support system subjected to dynamic loads in Kiirunavaara
University essay from Luleå tekniska universitet/GeoteknologiAbstract : LKAB’s underground mine in Kiirunavaara has experienced an increasing seismic activity the last ten years. This seismic activity is caused by the stress redistribution resulting from the mining method of large-scale sublevel caving. The energy from the seismic events propagate in the rock mass as seismic waves. READ MORE

5. Rockfalls from rock cuts beside Swedish railroads : A full scale fieldtest, to investigate rockfalls and how rock bounces
University essay from KTH/Jord- och bergmekanikAbstract : Rockfalls is a major problem around the world, if they occur in populated areas, they can cause major damage to infrastructure, injure or kill people. For this reason, it is important to be able to predict where the risk of rockfalls and how to prevent and protect populated areas from them. However, it is no easy task to predict rockfalls. READ MORE
