  2. 1. The Underground as a Storage Facility. Modelling of Nuclear Waste Repositories and Aquifer Thermal Energy Stores

    Author : Thomas Probert; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; exponential decay; modelling; fractured rock; classical mechanics; quantum mechanics; Mathematical and general theoretical physics; relativity; statistical physics; thermodynamics; Matematisk och allmän teoretisk fysik; klassisk mekanik; relativitet; kvantmekanik; gravitation; statistisk fysik; termodynamik; Environmental technology; pollution control; kontroll av utsläpp; Miljöteknik; conformal flow; heat as a tracer; KBS-3; stress field; temperature field; analytical solution; salt buoyancy; groundwater flow; nuclear waste repository; aquifer thermal energy storage; Fysicumarkivet A:1998:Probert;

    Abstract : The underground is a vast region, which is, too a large extent, unused by man. It has a large potential as a storage facility due to its vastness and availability. This thesis, which consists of eleven papers and reports, deals with nuclear waste repositories in solid rock and with aquifer thermal energy storage systems. READ MORE

  4. 2. Suitability of industrial residues for preventing acid rock drainage generation from waste rock

    Author : Elsa Nyström; Lena Alakangas; Hanna Kaasalainen; Christian Maurice; Päivi M. Kauppila; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geochemistry; Tillämpad geokemi;

    Abstract : One of the main and most challenging environmental problems related to mining is the generation of acid rock drainage (ARD), a leachate characterized by low pH and elevated concentrations of sulfate, metals, and metalloids formed when sulfide-bearing minerals are subjected to oxygen and water. During the operation of a mine, waste rock is often deposited in heaps and usually left under ambient conditions, enabling sulfides to oxidize. READ MORE

  5. 3. Strain quantifications in different tectonic scales using numerical modelling

    Author : Lukas Fuchs; Hemin Koyi; Susanne Buiter; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Deformation modelling; progressive and finite deformation; salt tectonics; down-built diapir; upper mantle; lithosphere-asthenosphere boundary; seismic anisotropy; plate-mantle de coupling; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

    Abstract : This thesis focuses on calculation of finite and progressive deformation in different tectonic scales using 2D numerical models with application to natural cases. Essentially, two major tectonic areas have been covered: a) salt tectonics and b) upper mantle deformation due to interaction between the lithosphere and asthenosphere. READ MORE

  6. 4. Grouting of Fractured Rock with Silica Sol; Grouting design based on penetration length

    Author : Johan Funehag; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grouting; hydraulic test; sand column; propagation; penetration length; pipe flow; aperture; transmissivity; colloidal silica; silica sol; rheology; gelling liquids; field study;

    Abstract : ABSTRACTRecent grouting projects in Sweden have concentrated on the grout itself. The only grout normally used in Sweden is cement-based. During the past 10 years, the acceptable flow of water into tunnels has been reduced significantly. The current requirements mean that an average fracture aperture of around 0. READ MORE

  7. 5. Grouting of Hard Rock with Gelling Liquids, Field and Laboratory Studies of Silica sol

    Author : Johan Funehag; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; aperture; penetration length; gelling liquids; field study; silica sol; colloidal silica; Grouting; propagation; hydraulic test; sand column; rheology; transmissivity;

    Abstract : Recent grouting projects in Sweden have concentrated on the grout itself. The only grout normally used in Sweden is a cement-based one. During the past 10 years, the acceptable flow of water into tunnels has been significantly reduced. The current requirements mean that an average fracture aperture of around 0. READ MORE
