  1. 1. Paleomagnetic and Thermomagnetic Studies on Rock Samples from COSC - 1 Drilling Project

    University essay from Uppsala universitet/Geofysik

    Author : Wanyi Li; [2022]
    Keywords : Scandinavian Caledonides; remanent magnetization; AF demagnetization; temperature dependent magnetic susceptibility; Skandinaviska Kaledoniderna; remanent magnetism; växelfältsavmagnetisering; temperaturberoende av magnetisk susceptibilitet;

    Abstract : The COSC-1 borehole located in the Lower Seve nappe of the Central Scandinavian Caledonides is intended to study the tectonic evolution of the Paleozoic orogen. The drilling project reached a depth of 2495.8m and obtained samples from different lithologal units of mica schist, amphibolite, gneiss, and mylonitic gneisses. READ MORE

  3. 2. Environmental and technical evaluation of cement reduction and test methods for fibre reinforced shotcrete in tunnels

    University essay from KTH/Betongbyggnad

    Author : Elin Brodd; Lina Östlund; [2022]
    Keywords : Shotcrete; Global Warming Potential; Environmental Product Declaration; Tunnel construction; Fibre reinforcement; Compressive strength; Residual strength; GGBS; Sprutbetong; Klimatpåverkan; Miljövarudeklaration; Tunnelbyggande; Fiberarmering; Tryckhållfasthet; Residualhållfasthet; Granulerad Masugnsslagg;

    Abstract : The dominating support method for hard rock tunnels today is use of fibre reinforced shotcrete in combination with rock bolts. The fibre reinforced shotcrete secures smaller blocks, while rock bolts are used to support larger blocks in the rock. Application of shotcrete is done by spraying against the rock surface using compressed air. READ MORE

  5. 4. A Geometallurgical Approach Towards the Correlation Between Rock Type Mineralogy and Grindability: A case study in Aitik mine, Sweden

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

    Author : Raoul Schmitt; [2021]
    Keywords : Geometallurgy; autogenous grinding; process mineralogy; grindability test; abrasion breakage; automated mineralogy;

    Abstract : Aitik is a large copper porphyry type deposit located in northern Sweden, currently exploited at an annual rate of approximately 45Mt. The ore's exceptionally low head grade of 0.22 % Cu and varying degrees of hardness across the entire deposit pose challenges to the two fully autogenous grinding lines, each of which comprises a 22.

  6. 5. An Investigation of the breakage process of particles : With help of experimental results and discrete element methods

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

    Author : Ronni Bashiry; [2021]
    Keywords : Geotechnical Engineering; Breakage; Fracture; Spherical particles; DEM; Modelling; Numerical modelling;

    Abstract : In this study the breakage mechanics of brittle glass marbles was investigated. The pro-cess was to firstly investigate them in laboratory environment. The marbles or specimens was loaded until a crushing breakage occurred in a single point load test called Single Sphere Point load test in this document. READ MORE
