1. Påldrivning: Jämförelse mellan luft- och vattendriven borrning : En utredning av jämförelser avseende slitage, logistik och driftkostnader
Kandidat-uppsats, KTH/Byggteknik och designSammanfattning : Skanska Grundläggning in Region Special wishes to gain an increased understanding of the extent to which it differs in the wear of percussion hammers and pilot drill crowns, depending on which driving medium is used in down-the-hole drilling, as well as logistical and economic aspects depending on the chosen method. Down-the-hole drilling means that the hammer works down in the borehole and forms one of the components at the far end of the drill string together with a drill bit. LÄS MER
2. Klimatsmarta transporter - En fallstudie av Norconsults tjänsteresor för geotekniska fältundersökningar
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystemSammanfattning : Global authorities and businesses around the world have come up with a joint climate goal, including strategies to reduce greenhouse gas emissions in an effort to fight and reach the “1.5 degrees” goal in time.

3. Alternativ till konventionell ovanjordsprängning i tätbebyggda områden
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Byggteknik och byggd miljöSammanfattning : For many constructions works, the removal of bedrock is required as an initial part of the production. Removing bedrock is complicated, takes a lot of time and entails many risks due to the vibrations that occur during the detonation. The risk of damaging nearby properties is impending. LÄS MER
4. VERTICAL ELLIPTICAL ACCESS-SHAFTS Geometrical optimisation through FE-modelling
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Geoteknik; Lunds universitet/Institutionen för byggvetenskaperSammanfattning : Urbanisation is causing densification of cities and more and more facilities are being placed in the underground to utilise the urban space as efficiently as possible. Access to the underground is obtained by constructing vertical access shafts. LÄS MER
5. Mineralogy and petrology of a drill core section from Borg, SW Norrköping – fracture fillings and tentative mineral reactions
Kandidat-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaperSammanfattning : During drilling at Borg, ca. 5 km southwest of central Norrköping, an unidentified fine-grained grey rock was encountered in contact with dark red granitic gneiss at 35m depth. The fine-grained grey rock occurs above the red granitic gneiss. LÄS MER
