  1. 1. Identification and strength classification of weakness zones in the Garpenberg mine based on measurement while drilling (MWD)

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Ioannis Peroulakis; [2022]
    Keywords : Drilling; MWD; Garpenberg; Mining; Geotechnics;

    Abstract : Boliden’s Garpenberg mine produces Zn-Pb-Ag(Cu-Au) using a sublevel stoping with pastefill mining method. The orebody is strongly affected by the existence of weakness zones mainly consisting of Talc Schist and Phlogopite Schist which affect the design, planning and production of the stope. READ MORE

  3. 2. Rock Strength Testing of Drill Core Samples From Kiirunavaara Below Level 1365

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Giorgios Doulamis; [2022]
    Keywords : Kiirunavaara; Point Load test; Leeb hardness test; intact rock strength; correlation factor;

    Abstract : The geotechnical parameters of the different lithologies are of great importance regarding mining, infrastructures development and safety. The main aims of this thesis project are the evaluation of the previously acquired point load tests (PLT) data and the acquisition of a larger set for the various lithologies and alterations.

  4. 3. Geochronology of gneisses adjacent to the Mylonite Zone in southwestern Sweden: evidence of a tectonic window?

    University essay from Lunds universitet/Geologiska institutionen

    Author : James Davies; [2020]
    Keywords : Geochronology; Hallandian orogeny; Mylonite Zone; Sveconorwegian orogeny; U-Pb; Idefjorden terrane; Eastern Segment; B-Bulan; Brobacka; Earth and Environmental Sciences;

    Abstract : The relationship between the Eastern Segment and Idefjorden terrane prior to the Sveconorwegian orogeny has long been debated. Evidence of a common history is minimal and localised; at the same time, the notion that the Sveconorwegian orogeny formed as a result of a collisional event is also disputed. READ MORE

  5. 4. Evaluation of influence from matedness on the peak shear strength of natural rock joints

    University essay from KTH/Byggvetenskap

    Author : Emil Andersson; [2019]
    Keywords : Rock joints; Peak shear strength; Matedness; Casagrande et al. criterion; Peak friction angle; Shear strength; Bergssprickor; Maximal skjuvhållfasthet; Passning; Casagrande et al. kriterium; Friktionsvinkel; Skjuvhållfasthet;

    Abstract : In Sweden, the rock mass is commonly used for construction of tunnels and caverns. The rockmass is also used as a foundation for large structures such as bridge abutments and dams. Forthese structures, the understanding of the rock mechanical properties play a key role for reachingan acceptable safety level and minimizing cost. READ MORE

  6. 5. Petrophysic of the Host-rock to the Ore in the Lovisa Mine, Bergslagen

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Oscar Gilljam Päärt; [2019]
    Keywords : Petrophysics; density; magnetic volume susceptibility; natural remanent magnetization; Bergslagen; lithology; Petrofysik; densitet; magnetisk susceptibilitet; naturlig magnetisk remanens; Bergslagen; lithologi;

    Abstract : The Bergslagen region has three base-metal mines operating today, and one of them is the Lovisa mine, which host a Zn-Pb-Ag deposit. The Lovisa mine is located in the Guldsmedshyttan area north of Lindesberg. READ MORE
