1. Method to statistically secure field test results for rock drilling tools
Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskapSammanfattning : The aim of this project is to find a statistical method that describes survival and outcome of a prototype drilling tool from several references and determine how many references are needed for a statistically secure result. The project also answers which variables that affects the outcome. LÄS MER
2. Stratigraphy and palaeoenvironment of the early Jurassic volcaniclastic strata at Djupadalsmölla, central Skåne, Sweden
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : From the almost 200 volcanic outcrops in the Central Skåne Volcanic Province (CSVP), only three are of volcaniclastic material. These volcanoclastics, and the transition to the underlying crystalline basement, have been investigated for the first time in a drill core (KBH2) from Djupadalsmölla in order to understand the stra-tigraphy, depositional process, age of deposition, and depositional environment.

3. Återvinning av hårdmetallstift : En studie av hårdmetallstiftens livscykel och hur volframet i stiften återvinns
Magister-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : I det moderna samhället finns det ett stort behov av metaller och mineraler som används i allt från mobiltelefoner till bilar. Dessa mineraler och metaller finns under marken och behöver grävas upp och genomgå förädlingsprocesser för att användas. LÄS MER
4. A Petrographic and Paragenetic Characterization of the Ertelien Ni-Cu Deposit (Norway)
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The escalating demand for metals driven by advancements in renewable energy technologies and hightech products has underscored the significance of understanding and characterizing ore deposits. This study focuses on the Ertelien Ni-Cu deposit in Norway, a region rich in nickel, cobalt, and copper resources—essential components for the transition to a sustainable energy future. LÄS MER
5. Electrification of rock drills : An initial study of an electromagnetic percussion concept
Master-uppsats, Linköpings universitet/Fluida och mekatroniska systemSammanfattning : The world is looking for greener solutions and so is the mining industry. This quest has led to the question whether it is possible to have a completely electric rock drill. This work carries out an initial exploration of completely electrified percussion. LÄS MER
