  1. 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 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

  3. 2. Trädens växtplats i staden : jämförelse mellan två växtbäddsystem med fokus på konstruktion och tillväxt

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Johanna Pantulin Nordlund; [2023]
    Keywords : stadsträd; klimatanpassning; markförhållanden; strukturell jord; skelettjord; Stockholm; strukturella system; plastceller; växtceller; Milford;

    Abstract : Extrema väderförhållanden blir allt vanligare på grund av klimatförändringarna vilket leder till ökade risker för värmeböljor, skyfall och torka. Samtidigt växer världens städer och fler människor flyttar in till mer urbana miljöer. För att klara ett förändrat klimat behöver städerna anpassas. READ MORE

  4. 3. Application of ERT for Quality Assurance in Jet Grouting Columns; A development of an alternative quality control

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Edvin Nilsagård; Rebecka Knutsson; [2022]
    Keywords : ert; jet grouting; quality control; pygimli; res2dinv; resistivity; Technology and Engineering;

    Abstract : With the increased urbanization major cities are facing, expansion of larger facilities and households are inevitable. Expansion means larger areas of the surface needs to be used where the risk of varying subsurface soil properties increases with larger surface areas. READ MORE

  5. 4. A comparison of 2D and 3D resistivity surveys for 3D inversion imaging

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Julia Cavell; [2022]
    Keywords : ;

    Abstract : Following study focuses on electrical resistivity surveying and how it can be used as an exploration method to increase knowledge of subsurface structures. Future scenarios with increasing population and rapid urbani-zation, put high demands on reliable infrastructure; safe foundations, un-derground structures, environmental safety and access to resources.

  6. 5. 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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Oludare Joseph Olufe; [2021]
    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
