  1. 1. Adapted data collection in field utilizing RMR and the Q-system

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

    Author : Amanda Olsson; [2024]
    Keywords : Rock mass classification; Q-slope; SMR; Slope stability;

    Abstract : The focus on slope stability has increased rapidly in Norway over the last years due to several unwanted landslides. In Norway, the most used method today to classify the rock mass and to determine the required reinforcement, is the Q-system. In addition to that the RMR method is also a commonly used method.

  3. 2. Evaluation of SLAM based mobile laser scanning and terrestrial laser scanning in the Kiruna mine : A comparison between the Emesent Hovermap HF1 mobile laser scanner and the Faro Laser Scanner Focus3D X 330 terrestrial laser scanner

    University essay from Högskolan i Gävle/Samhällsbyggnad

    Author : Claes Gustafsson; [2023]
    Keywords : Terrestrial laser scanning; mobile laser scanning; simultaneous localization and mapping; underground mapping; Kiruna mine.;

    Abstract : The mining industry has over the last few decades seen a drastic increase in the usage of laser scanning technologies as a way of creating 3D maps of the mines being exploited. Underground mapping in places such as mines has become more prevalent as the technology has progressed and made it easier to generate highly detailed point clouds faster. READ MORE

  4. 3. Teleoperation of an Autonomous Ground-Penetrating Radar for Non-Destructive Surveying: Design and Implementation

    University essay from Umeå universitet/Institutionen för fysik

    Author : Rasmus Beyer; [2023]
    Keywords : Autonomous; GPR; Robotics;

    Abstract : A lot of features that need to be scanned underground should not be disturbed, from waterlines to unmarked graves. A non-invasive way of probing underground is Ground-Penetrating Radar (GPR). GPR finds differences in materials with radar waves. However, GPR is human-operated and its position is generally determined with a GPS. READ MORE

  5. 4. 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

  6. 5. Hydrogen Production and Storage Optimization based on Technical and Financial Conditions : A study of hydrogen strategies focusing on demand and integration of wind power.

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Hanna Langels; Oskar Syrjä; [2021]
    Keywords : Hydrogen; hydrogen energy system; hydrogen production; hydrogen storage; large-scale storage; underground storage; vessels; LRC; hydrogen application; hydrogen strategies; hydrogen transition; offshore wind energy; electricity grid; electricity price; volatile electricity prices; renewable energy; hydrogen refueling station; hydrogen port; green hydrogen; hydrogen trucks; hydrogen forklifts; fuel cells; electrolysis; alkaline electrolyzer; PEM electrolyzer; levelized cost of hydrogen; LCOH; Vätgas; vätgassystem; vätgasproduktion; vätgaslagring; storskalig vätgaslagring; bergrum; vätgasapplikationer; vätgasstrategi; vätgasomställning; grön omställning; havsbaserad vindkraft; volatila elpriser; elnätet; förnybar energi; vätgastankstation; vätgasmack; vätgashamn; grön vätgas; vätgaslastbilar; vätgastruckar; bränsleceller; elektrolys; alkalisk elektrolysör; PEM elektrolysör;

    Abstract : There has recently been an increased interest in hydrogen, both as a solution for seasonal energy storage but also for implementations in various industries and as fuel for vehicles. The transition to a society less dependent on fossil fuels highlights the need for new solutions where hydrogen is predicted to play a key role. READ MORE
