  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. The future of geothermal energy in Europe

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Susana Barquín del Rosario; [2022]
    Keywords : Geothermal Energy; Opportunities; Risks; Barriers; Development scenarios; Status in Europe; Potential;

    Abstract : In this paper it is investigated the role that geothermal energy could play in theenergy mix, to meet new system requirements. As any other source, geothermal energy harnessing implies a number of risksmainly related to induced seismicity and landslides, together with the releaseof as greenhouse gases and metal salts.

    Keywords : Drift stability analysis; underground excavation reinforcement; underground mining stability assessment; geologic structures; wedges modelling; rock mechanical analysis; Unwedge program; Dips program;

    Abstract : Study of Production Drifts Stability and Assessment of Reinforcement Requirements at LKAB Konsuln Test-Mine Levels 436 and 486 Using Geologic Structures Data, and Modelling Software - Dips and Unwedge:  a Part of dp1 Project (Mine Layout and Technology) of the Sustainable Underground Mining (Sum) Project Oludare Joseph Olufe Global population has been on exponential increase over the past half century. The population explosion is driving massive urbanization and infrastructure developments across the globe, which result in huge demand for metals, especially steel. READ MORE

  6. 5. 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
