1. 1. Uranium Mineralizations at Kiirunavaara,Northernmost Sweden

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Diego Segovia Menard; [2022]
   Nyckelord :kiirunavaara; uranium; EPMA; water; hydrothermal;

   Sammanfattning : In recent years, a variably high amount of uranium (U) and radon (Rn) were found in the water and airof the Kiirunavaara mine in Kiruna, northern Sweden. The Swedish Agency for Marine and WaterManagement (Havs och vattenmyndigheten) has maximum limits for “special polluting substances” inwater that is released to natural recipients (HVMFS 2019:25), therefore, the mining company LKAB,owner and operator of the Kiirunavaara mine, decided to conduct a study to investigate the issueregarding these findings, triggering this master thesis.

3. 2. Limitations of the Ground Reaction Curve Concept for Shallow Tunnels Under Anisotropic In-situ Stress Conditions

   Uppsats för yrkesexamina på avancerad nivå, KTH/Jord- och bergmekanik

   Författare :Diego Lope Álvarez; [2012]
   Nyckelord :Ground reaction curve; shallow tunnels; isotropic stress conditions; anisotropic stress conditions; analytical solution;

   Sammanfattning : The deep mining industry and civil engineering need to perform rock stability analyses during excavation projects. These analyses are closely related with displacements in tunnel contours. The ground reaction curve is a powerful tool to characterize these displacements that is widely used in the New Austrian Tunneling Method. LÄS MER
