  3. 2. 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 naturresurser

    Author : Manuel Alberto Fuentes Espinoza; [2023]
    Keywords : Structurally controlled rockfalls; rockfalls due to seismic shaking; sublevel caving; fork layout; Unwedge; wedge analysis; deterministic analysis; probabilistic analysis;

    Abstract : 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

  4. 3. Borehole Dimension Impact on LHD Operation in Malmberget Mine

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Markus Danielsson; [2016]
    Keywords : LHD; sublevel caving; fragmentation;

    Abstract : Sublevel caving is a highly mechanizable mass mining method normally utilized in large, steeply dipping orebodies. The fragmented ore flows freely, aided by gravity, down to the drawpoint while the surrounding waste rock caves in due to induced stresses and gravity. READ MORE

  5. 4. Induced Seismicity in the Dannemora Mine, Sweden

    University essay from Uppsala universitet/Geofysik

    Author : Joanna Holmgren; [2015]
    Keywords : Mining-induced seismicity; phase picking; particle motion; local earthquake tomography; correlation; local magnitude;

    Abstract : Induced seismicity is a common phenomenon that occurs as soon as the stress state in the subsurface is externally altered in a way that faults are destabilized. It is especially problematic in stable tectonic regions where the area is not used to earthquakes; the infrastructure is not built to withstand ground movement and thus when the induced seismicity occurs damage can follow.
